On systems, using regulators to supply power to devices, if the REGULATOR
Kconfig option is disabled, regulator API stubs will be used, which often
suffices to bring a default configuration up. If REGULATOR is enabled but
respective regulator drivers are inactive, the real regulator API calls
will be used, which in the absence of drivers will fail to provide
services. This patch prevents such a problem on sh-mobile boards by
forcing REGULATOR_FIXED_VOLTAGE on if REGULATOR is selected.

The STI hardware is based on a single 48-bit 32kHz
counter that together with two individual compare
registers can generate interrupts. There are no
timer operating modes selectable which means that
the timer can not clear on match.

This driver is providing clocksource support for the
48-bit counter. Clockevents are also supported using
the same timer in oneshot mode.

DT support is still on the TODO for the GPIO driver,

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.

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.
