The GIC support code is heavily using the fact that hardware
implementations are exposing banked registers. Unfortunately, it
looks like at least one GIC implementation (EXYNOS) offers both
the distributor and the CPU interfaces at different addresses,
depending on the CPU.
This problem is solved by allowing the distributor and CPU interface
addresses to be per-cpu variables for the platforms that require it.
The EXYNOS code is updated not to mess with the GIC internals while
handling interrupts, and struct gic_chip_data is back to being private.
The DT binding for the gic is updated to allow an optional "cpu-offset"
value, which is used to compute the various base addresses.
Finally, a new config option (GIC_NON_BANKED) is used to control this
feature, so the overhead is only present on kernels compiled with
support for EXYNOS.
Tested on Origen (EXYNOS4) and Panda (OMAP4).

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.

Pave the way for adding PM support on S5P64X0, which is more similar
to the S3C64XX series than the S5P series. Hence, the common pm code
(containing dummy functions) should not be used for S5P64X0.

This patch adds common code to enable support of GPIO interrupt on
S5P SoCs.
The total number of GPIO pins is quite large on S5P SoCs. Registering
irq support for all of them would be a resource waste. Because of that
the interrupt support for standard GPIO pins is registered dynamically
by the s5p_register_gpio_interrupt() function.
