ARM: SAMSUNG: Move common save/restore helpers to separate file
To separate legacy PM code from generic helpers, this patch moves the
generic register save/restore helpers to a new file called pm-common.c
that is compiled always when CONFIG_PM_SLEEP is enabled, to allow
platforms that do not want to use the legacy PM code use the generic
helpers.

Not all Samsung SoC platforms are going to use the legacy Samsung PM

As per the Exynos5250 User Manual:
When there are pending interrupt events, WFI/WFE instruction are
ignored. To cancel the power-down sequence follow these steps:
1) Disable system power-down using CENTRAL_SEQ_CONFIGURATION register
2) Clear WAKEUP_STAT register
3) Enable interrupt service routine for CPU
Code for early wakeup for exynos already exists. Remove the panic
on suspend failure, clear the wakeup state register and return 1
from cpu_suspend to indicate a failed suspend (to a user daemon).
Older Samsung SoCs have similar panics and I have removed them all.

ARM: pm: allow suspend finisher to return error codes
There are SoCs where attempting to enter a low power state is ignored,
and the CPU continues executing instructions with all state preserved.
It is over-complex at that point to disable the MMU just to call the
resume path.
Instead, allow the suspend finisher to return error codes to abort
suspend in this circumstance, where the cpu_suspend internals will then
unwind the saved state on the stack. Also omit the tlb flush as no
changes to the page tables will have happened.
