mfd: db8500-prcmu: Fold dbx500 header into db8500

Browse source 
Move the DBx500 PRCMU definitions into the DB8500 PRCMU
header and delete the wrapper header.

Convert users of simple PRCMU wrappers to call the DB8500 helpers
directly.

The dbx500-prcmu.h header was the result of an earlier attempt to
abstract several DBx5x SoC PRCMU units to use the same abstract
header. They are deleted from the kernel and this is not just
causing maintenance burden and build errors.

The stub code is using -ENOSYS in a way checkpatch complains about
so replace these with -EINVAL while we're at it.
