MIPS: malta: Use img-ascii-lcd driver for LCD display
Remove the Malta display platform code in favour of probing the img-ascii-lcd driver via device tree. This reduces the amount of platform code & the img-ascii-lcd driver offers us advantages in terms of code sharing with other boards & functionality such as changing the displayed message via sysfs. Defconfigs are untouched because the driver already defaults y on when CONFIG_MIPS_MALTA=y.

MIPS: Use mips_gic_present() in place of gic_present
In preparation for removing the gic_present global variable, switch to using the mips_gic_present() function instead. For the most part this is a straightforward substitution. In cases which previously wrapped the GIC case in an #ifdef CONFIG_MIPS_GIC that #ifdef has been removed, since mips_gic_present() will return a compile-time constant false allowing the affected code to be optimised out anyway.

MIPS/Malta: Probe gic-timer via devicetree
The Malta platform is the only platform remaining to probe the GIC clocksource via gic_clocksource_init. This route hardcodes an expected virq number based on MIPS_GIC_IRQ_BASE, which can be fragile to the eventual virq layout. Instread, probe the driver using the preferred and more modern devicetree method.
Before the driver is probed, set the "clock-frequency" property of the devicetree node to the value detected by Malta platform code.

MIPS: malta-time: Take seconds into account
When estimating the clock frequency based on the RTC, take seconds into account in case the Update In Progress (UIP) bit wasn't seen. This can happen in virtual machines (which may get pre-empted by the hypervisor at inopportune times) with QEMU emulating the RTC (and in fact not setting the UIP bit for very long), especially on slow hosts such as FPGA systems and hardware emulators. This results in several seconds actually having elapsed before seeing the UIP bit instead of just one second, and exaggerated timer frequencies.
While updating the comments, they're also fixed to match the code in that the rising edge of the update flag is detected first, not the falling edge.
The rising edge gives a more precise point to read the counters in a virtualised system than the falling edge, resulting in a more accurate frequency.
It does however mean that we have to also wait for the falling edge before doing the read of the RTC seconds register, otherwise it seems to be possible in slow hardware emulation to stray into the interval when the RTC time is undefined during the update (at least 244uS after the rising edge of the update flag). This can result in both seconds values reading the same, and it wrapping to 60 seconds, vastly underestimating the frequency.

MIPS: malta-time: Start GIC count before syncing to RTC
The sampling of the GIC counter on Malta after observing a rising edge of the RTC update flag differs slightly between the first and second sample, with the first sample also calling gic_start_count(). The two samples should really be taken as similarly as possible to get the most accurate figure, so move the gic_start_count() call before detecting the rising edge.

MIPS: Malta: Don't reinitialise RTC
On Malta, since commit a87ea88d8f6c ("MIPS: Malta: initialise the RTC at boot"), the RTC is reinitialised and forced into binary coded decimal (BCD) mode during init, even if the bootloader has already initialised it, and may even have already put it into binary mode (as YAMON does). This corrupts the current time, can result in the RTC seconds being an invalid BCD (e.g. 0x1a..0x1f) for up to 6 seconds, as well as confusing YAMON for a while after reset, enough for it to report timeouts when attempting to load from TFTP (it actually uses the RTC in that code).
Therefore only initialise the RTC to the extent that is necessary so that Linux avoids interfering with the bootloader setup, while also allowing it to estimate the CPU frequency without hanging, without a bootloader necessarily having done anything with the RTC (for example when the kernel is loaded via EJTAG).
The divider control is configured for a 32KHZ reference clock if necessary, and the SET bit of the RTC_CONTROL register is cleared if necessary without changing any other bits (this bit will be set when coming out of reset if the battery has been disconnected).

MIPS: Malta: Make GIC FDC IRQ workaround Malta specific
Wider testing reveals that the Fast Debug Channel (FDC) interrupt is routed through the GIC just fine on Pistachio SoC, even though it contains interAptiv cores. Clearly the FDC interrupt routing problems previously observed on interAptiv and proAptiv cores are specific to the Malta FPGA bitstreams.
Move the workaround for interAptiv and proAptiv out of gic_get_c0_fdc_int() in the GIC irqchip driver into Malta's get_c0_fdc_int() platform callback, to allow the Pistachio SoC to use the FDC interrupt.

irqchip: mips-gic: Support local interrupts
The MIPS GIC supports 7 local interrupts, 2 of which are the GIC local watchdog and count/compare timer. The remainder are CPU interrupts which may optionally be re-routed through the GIC. GIC hardware IRQs 0-6 are now used for local interrupts while hardware IRQs 7+ are used for external (shared) interrupts.
Note that the 5 CPU interrupts may not be re-routable through the GIC. In that case mapping will fail and the vectors reported in C0_IntCtl should be used instead. gic_get_c0_compare_int() and gic_get_c0_perfcount_int() will return the correct IRQ number to use for the C0 timer and perfcounter interrupts based on the routability of those interrupts through the GIC.
A separate irq_chip, with callbacks that mask/unmask the local interrupt on all CPUs, is used for the C0 timer and performance counter interrupts since all other platforms do not use the percpu IRQ API for those interrupts.
Malta, SEAD-3, and the GIC clockevent driver have been updated to use local interrupts and the R4K clockevent driver has been updated to poll for C0 timer interrupts through the GIC when the GIC is present.
