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.

The following commits break cpuidle on SH-Mobile ARM:

46bcfad7 cpuidle: Single/Global registration of idle states
e978aa7d cpuidle: Move dev->last_residency update to driver enter routine; remove dev->last_state

This patch remedies these issues by up-porting the SH-Mobile
code to fit with the above introduced framework changes.

It is worth noting that the new code becomes significantly cleaner,
so these framework changes are very welcome. At the same time this
breakage could probably have been avoided by grepping for "last_state"
and "cpuidle_register_driver".

This patch makes the cpuidle_states structure global (single copy)
instead of per-cpu. The statistics needed on per-cpu basis
by the governor are kept per-cpu. This simplifies the cpuidle
subsystem as state registration is done by single cpu only.
Having single copy of cpuidle_states saves memory. Rare case
of asymmetric C-states can be handled within the cpuidle driver
and architectures such as POWER do not have asymmetric C-states.

Having single/global registration of all the idle states,
dynamic C-state transitions on x86 are handled by
the boot cpu. Here, the boot cpu  would disable all the devices,
re-populate the states and later enable all the devices,
irrespective of the cpu that would receive the notification first.

This is the first step towards global registration of cpuidle
states. The statistics used primarily by the governor are per-cpu
and have to be split from rest of the fields inside cpuidle_state,
which would be made global i.e. single copy. The driver_data field
is also per-cpu and moved.

Cpuidle governor only suggests the state to enter using the
governor->select() interface, but allows the low level driver to
override the recommended state. The actual entered state
may be different because of software or hardware demotion. Software
demotion is done by the back-end cpuidle driver and can be accounted
correctly. Current cpuidle code uses last_state field to capture the
actual state entered and based on that updates the statistics for the
state entered.

Ideally the driver enter routine should update the counters,
and it should return the state actually entered rather than the time
spent there. The generic cpuidle code should simply handle where
the counters live in the sysfs namespace, not updating the counters.

The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has
made for plaforms based on EXYNOS4 SoCs. But since upcoming
Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most
codes in current mach-exynos4, one mach-exynos directory will
be used for them.

This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos)
but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to
avoid changing in driver side.

zero means an error. However, zero is also returned when context has
