mfd: db8500-prcmu: Support U8420-sysclk firmware
There is a distinct version of the Ux500 U8420 variant with "sysclk", as can be seen from the vendor code that didn't make it upstream, this firmware lacks the ULPPLL (ultra-low power phase locked loop) which in effect means that the timer clock is instead wired to the 32768 Hz always-on clock.
This has some repercussions when enabling the timer clock as the code as it stands will disable the timer clock on these platforms (lacking the so-called "doze mode") and obtaining the wrong rate of the timer clock.
The timer frequency is of course needed very early in the boot, and as a consequence, we need to shuffle around the early PRCMU init code: whereas in the past we did not need to look up the PRCMU firmware version in the early init, but now we need to know the version before the core system timers are registered so we restructure the platform callbacks to the PRCMU so as not to take any arguments and instead look up the resources it needs directly from the device tree when initializing.
As we do not yet support any platforms using this firmware it is not a regression, but as PostmarketOS is starting to support products with this firmware we need to fix this up.
The low rate of 32kHz also makes the MTU timer unsuitable as delay timer but this needs to be fixed in a separate patch.

The PRCMU devices are getting populated from the MFD driver and that is enough for them to come up. We already have an early quirk for the things that need to happen really early and the PRCMU timer that need to be registered really early will find its own node just fine as the timer/clocksource subsystem looks through the whole device tree for compatible nodes.

Commit 2b05f6ae1ee5 ("ARM: ux500: remove PMU IRQ bouncer") deleted some code to bounce and work around the weird PMU IRQs in the DB8500 ASIC, but did a semantic mistake: since the auxdata was now unused, the call to of_platform_populate() was removed, but this does not work: the default platform population will only kick in if .init_machine() is assigned NULL, and since the U8540 was still using the callback that was not the case.
Fix this by reinstating the call to of_platform_populate(), but pass NULL as auxdata.

ARM: ux500: Fix regression while init PM domains
The commit afece3ab9a36 ("PM / Domains: Add time accounting to various genpd states") causes a boot regression for ux500.
The problem occurs when the ux500 machine code calls pm_genpd_init(), which since the above change triggers a call to ktime_get(). More precisely, because ux500 initializes PM domains in the init_IRQ() phase of the boot, timekeeping has not yet been initialized.
Fix the problem by moving the initialization of the PM domains to after timekeeping has been initialized.

drivers/perf: arm_pmu: Request PMU SPIs with IRQF_PER_CPU
Since the PMU register interface is banked per CPU, CPU PMU interrrupts cannot be handled by a CPU other than the one with the PMU asserting the interrupt. This means that migrating PMU SPIs, as we do during a CPU hotplug operation doesn't make any sense and can lead to the IRQ being disabled entirely if we route a spurious IRQ to the new affinity target.
This has been observed in practice on AMD Seattle, where CPUs on the non-boot cluster appear to take a spurious PMU IRQ when coming online, which is routed to CPU0 where it cannot be handled.
This patch passes IRQF_PERCPU for PMU SPIs and forcefully sets their affinity prior to requesting them, ensuring that they cannot be migrated during hotplug events. This interacts badly with the DB8500 erratum workaround that ping-pongs the interrupt affinity from the handler, so we avoid passing IRQF_PERCPU in that case by allowing the IRQ flags to be overridden in the platdata.

ARM: ux500: resume the second core properly
The pen hold/release scheme was copied over to Ux500 from the ARM reference designs like most of these at the time. It is not needed at all, and was mostly removed in commit c00def71efd9 "ARM: ux500: simplify secondary CPU boot".
However on the suspend/resume path and hot plug/unplug of CPUs, the .cpu_die() callback was still waiting for the pen to be released which made it spin forever and the second core never come back online after suspend/resume.
Fix this by simply replacing the strange custom .cpu_die() with a oneline wfi() just like e.g. the qcom platform does. This fixes the issue and makes the second core come up properly after suspend/resume.
As a side effect, this rids us of the completely surplus local setup.h and hotplug.c files, and we just compile this into platsmp.c with everything else SMP.

ARM: ux500: move soc_id driver to drivers/soc
As the ux500 id code is basically a standalone driver, we can move it out of the arch code into drivers/soc/ux500.
This is a user-visible change, as it moves all the devices in sysfs from /sys/devices/soc0/ to /sys/devices/ and leaves the soc0 node as a separate device.
Originally the idea was to put all on-chip devices under the soc node, and ux500 was the first platform to have this device, but later platforms almost all didn't follow that pattern, so this makes the platform do the same thing as everyone else.
Since the platform is really obsolete now, I am optimistic that nothing will break after moving the devices around.
As the SoC driver no longer has access to the private header files, I'm changing the code to instead look up the address of the backupram from devicetree, which is a good idea anyway.
Finally, having a separate Kconfig symbol means the driver is now optional and could even be a loadable module rather than always being built-in if we allowed that for soc_device.

ARM: ux500: call ux500_setup_id later
ux500_setup_id is currently called from u8500_map_io(), which is really early, but nothing relies on the ID any more, other than a printk message that is not really all that important to have early during boot.
If we move the call to ux500_setup_id() into ux500_soc_device_init(), that file becomes usuable almost entirely standalone, and we can kill off the u8500_map_io() callback as it just does the default debug_ll_io_init() now.

ARM: ux500: move ab8500_regulator_plat_data into driver
There is only one instance of ab8500_regulator_platform_data, and it's safe to assume we won't ever merge another one, so it's rather pointless to pass it through multiple levels of platform data pointers.
This moves the structure and everything referenced by it into the driver that uses it.

ARM: ux500: simplify secondary CPU boot
This removes a lot of ancient cruft from the Ux500 SMP boot. Instead of the pen grab/release, just point the ROM to secondary_boot() and start the second CPU there, then send the IPI.
Use our own SMP enable method. This enables us to remove the last static mapping and get both CPUs booting properly.
Tested this and it just works.
