Add GPIO-only r8a7779 PFC support V2.
Only regular GPIOs are supported at this time. GPIO_FN are not
supported because they require variable bit width support in be
the shared pfc code.

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.

R8A7740 GIC can not get external IRQx interrupt directly
without GIC - INTC demux support.
Current AG5 is using GIC - INTCS demux with
special irq relocation. but GIC - INTCA demux
is still not supported and it needs irq number re-mapping.
OTOH, normal INTC support as before is very enough for R8A7740,
because it is not SMP CPU.
This patch adds INTCA/INTCS support instead of GIC.

This patch adds initial support for Renesas SH-Mobile AG5.
At this point the AG5 CPU support is limited to the ARM
core, SCIF serial and a CMT timer together with L2 cache
and the GIC. The AG5EVM board also supports Ethernet.
Future patches will add support for GPIO, INTCS, CPGA
and platform data / driver updates for devices such as
IIC, LCDC, FSI, KEYSC, CEU and SDHI among others.
The code in entry-macro.S will be cleaned up when the
ARM IRQ demux code improvements have been merged.
Depends on the AG5EVM mach-type recently registered but
not yet present in arch/arm/tools/mach-types.
As the AG5EVM board comes with 512MiB memory it is
recommended to turn on HIGHMEM.
Many thanks to Yoshii-san for initial bring up.

Presently each one of the CPUs manually selects the same feature set, and
there's a reasonable expectation that none of these will change for
future CPUs in the SH-Mobile / R-Mobile family, so we move those over to
the top-level ARCH_SHMOBILE.
While we're at it, all of the CPUs support optional GPIOs via the PFC,
do not have I/O ports, and expect sparse IRQ, so we bring the
configuration in line across the board.
This more or less brings the ARM-based parts in sync with their SH
counterparts.

Many of the config bit are presently duplicated between the platforms,
which will gradually cleaned up through centralization. For the moment we
expose some new INTC features through drivers/sh/Kconfig that the ARM
platforms presently don't enable, so make it generally available.
