ARM: shmobile: Enable ARM_GLOBAL_TIMER on Cortex-A9 MPCore SoCs

SH-Mobile AG5 and R-Car H1 SoCs are based on the Cortex-A9 MPCore, which
includes a global timer.

Enable the ARM global timer on these SoCs, which will be used for:
- the scheduler clock, improving scheduler accuracy from 10 ms to 3 or
4 ns,
- delay loops, allowing removal of calls to shmobile_init_delay() from
the corresponding machine vectors.

Note that when using an old DTB lacking the global timer, the kernel
will still work. However, loops-per-jiffies will no longer be preset,
and the delay loop will need to be calibrated during boot.

ARM: shmobile: sh73a0 legacy: Set .control_parent for all irqpin instances

The sh73a0 INTC can't mask interrupts properly most likely due to a
hardware bug. Set the .control_parent flag to delegate masking to the
parent interrupt controller, like was already done for irqpin1.

Without this, accessing the three-axis digital accelerometer ADXL345
on kzm9g through /dev/input/event1 causes an interrupt storm, which
requires a power-cycle to recover from.

This was inspired by a patch for arch/arm/boot/dts/sh73a0.dtsi from

ARM: shmobile: Add early debugging support using SCIF(A)

Add serial port debug macros for the SCIF(A) serial ports.
This includes all supported shmobile SoCs, except for EMEV2.

The configuration logic (both Kconfig and #ifdef) is more complicated than
one would expect, for several reasons:
1. Not all SoCs have the same serial devices, and they're not always
at the same addresses.
2. There are two different types: SCIF and SCIFA. Fortunately they can
easily be distinguished by physical address.
3. Not all boards use the same serial port for the console.
The defaults correspond to the boards that are supported in
mainline. If you want to use a different serial port, just change
the value of CONFIG_DEBUG_UART_PHYS, and the rest will auto-adapt.
4. debug_ll_io_init() maps the SCIF(A) registers to a fixed virtual
address. 0xfdxxxxxx was chosen, as it should lie below VMALLOC_END
= 0xff000000, and must not conflict with the 2 MiB reserved region
at PCI_IO_VIRT_BASE = 0xfee00000.
- On SoCs not using the legacy machine_desc.map_io(),
debug_ll_io_init() is called by the ARM core code.
- On SoCs using the legacy machine_desc.map_io(),
debug_ll_io_init() must be called explicitly. Calls are added
for r8a7740, r8a7779, sh7372, and sh73a0.

This was derived from the r8a7790 version by Laurent Pinchart.

According to the datasheet, the transfer rate is derived from the HP
clock (which runs at 104 MHz) divided by two. Hence
i2c_sh_mobile_platform_data.clks_per_count should be set to two.

Now probing succeeds, and i2c works:

The naming convention of this driver was always under the scanner, people
complained that it should have a more generic name than cpu0, as it manages all
CPUs that are sharing clock lines.

Also, in future it will be modified to support any number of clusters with
separate clock/voltage lines.

Lets rename it to 'cpufreq_dt' from 'cpufreq_cpu0'.
