This patch adds support Power Domain for S5PV310 and S5PC210.

This patch is applied according to the commit 1a8e41cd67
(ARM: 6395/1: VExpress: Set bit 22 in the PL310 (cache controller) AuxCtlr register).
Actually, S5PV310 has same cache controller(PL310).
Following is from Catalin Marinas' commit.
Clearing bit 22 in the PL310 Auxiliary Control register (shared
attribute override enable) has the side effect of transforming Normal
Shared Non-cacheable reads into Cacheable no-allocate reads.
Coherent DMA buffers in Linux always have a Cacheable alias via the
kernel linear mapping and the processor can speculatively load cache
lines into the PL310 controller. With bit 22 cleared, Non-cacheable
reads would unexpectedly hit such cache lines leading to buffer
corruption.

This patch implements Power Domain control based on Runtime PM framework.
Each Power Domain is represented by a Power Domain device and the devices
belong to these Power Domains should be set as a child device of the Power
Domain devices. The corresponding drivers of the devices should implement
Runtime PM to control the Power Domains.

In arch/x86/kernel/microcode_intel.c::generic_load_microcode()
we have this:
while (leftover) {
...
if (get_ucode_data(mc, ucode_ptr, mc_size) ||
microcode_sanity_check(mc) < 0) {
vfree(mc);
break;
}
...
}
if (mc)
vfree(mc);
This will cause a double free of 'mc'. This patch fixes that by
just removing the vfree() call in the loop since 'mc' will be
freed nicely just after we break out of the loop.
There's also a second change in the patch. I noticed a lot of
checks for pointers being NULL before passing them to vfree().
That's completely redundant since vfree() deals gracefully with
being passed a NULL pointer. Removing the redundant checks
yields a nice size decrease for the object file.
