[ARM] 3802/1: S3C24XX: PM tidy up cache flushing

Change to using flush_cache_all() in pm.c and
also remove the need to flush the cache in the
PM code.

This changes the sleep.S code to have an entry
to store the registers for resume, and then a
second entry (after the caches are cleaned)
to do the suspend and resume.
