Add support for generic power domain for Exynos4 platforms and remove the
Samsung specific power domain control for Exynos4.

The generic power domain infrastructure is used to control the power domains
available on Exynos4. For non-dt platforms, the power domains are statically
instantiated. For dt platforms, the power domain nodes found in the device
tree are instantiated.

This patch introduces common.[ch] which are used only in the
arch/arm/mach-exynos/ directory. The common.c file merges
the cpu.c, init.c, irq-combiner.c and irq-eint.c files which
are used commonly on EXYNOS SoCs and the common.h file replaces
with plat/exynos4.h file.

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.
