This patch moves r8a7779_init_irq_xxx() to setup code,
and remove intc-r8a7779.
Now, r8a7779_init_irq_extpin() uses
platform_device_register_resndata() instead of
platform_device_register()

Current Marzen is using DT booting,
and r8a7779.dtsi already has GIC settings.
So, we can remove the C version of the GIC setup code,
instead rely on GIC information provided by DT.

Now when the intc-irqpin driver is used for external
IRQ pins on r8a7779 it possible to get rid of unused
INTC headers mach/intc.h and linux/sh_intc.h.

The platform data for the INTC irq pin driver
seems to be global symbols, make it static to
allow multi-soc build.

Update the r8a7779 IRQ code to make use of the
INTC External IRQ pin driver for external
interrupt pins IRQ0 -> IRQ3.
The r8a7779 SoC can like older SH SoCs configure
to use the IRQ0 -> IRQ3 signals as individual
interrupts or a combined IRL mode.
Without this patch the r8a7779 SoC code does
not fully support external IRQ pins in individual
IRQ mode. The r8a7779 PFC code does not yet have
gpio_to_irq() support so no need to update such
code.
At this point the DT reference implementations
are not covered. In the future such code shall
tie in the INTC External IRQ pin driver via
DT, so this kind of verbose code is not needed
for the long term DT case.

This allows the GIC interrupt controller of the r8a7779 SoC to be
initialised using a flattened device tree blob.

v3
* Fix copy-paste error and use unique reg values for each CPU
v2
As suggested by Mark Rutland
* Add reg and device_type to cpus
* Remove #address-cells from gic

Now that we have GIC moved to drivers/irqchip and all GIC DT init for
platforms using irqchip_init, move gic.h and update the remaining
includes.

ARM is moving to stricter checks on readl/write functions,
so we need to use the correct types everywhere.
This patch is a bit ugly for shmobile, which is the only platform
that just uses integer literals all over the place, but I can't
see a better way to do this.

Several platforms incorrectly use __io() for casting to 'void __iomem *'.
This converts all of those uses to use the common IOMEM macro.

Initial support for the r8a7779 SoC and the Marzen board (V2).
Only SCIF ports and the TMU are supported at this point.
To keep things simple only entity-mapped virt-to-phys mappings
are supported. This forces drivers and other SoC glue code to
make use of ioremap(). We cannot support early serial console
due to virtual address space collisions with the ARM kernel.
