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.

Move the call to cpu_suspend into C code, and noticing that all the
s3c_cpu_save implementations are now identical, we can move this
into the common samsung code.

The gpio-bank-X header files of S3C64XX have definitions
which can be substituted by other common GPIO API.

Move the core S3C64XX support to mach-s3c64xx as it is unlikely to be used
outside of this directory. Also move the SoC header files in with it.
This includes the clock, cpu, cpufreq, dma, gpiolib and pll support.
