Now that we have a shared API between the DB8500 and DB5500
PRCMU's, switch to using this neutral API instead. We delete the
parts of db8500-prcmu.h that is now PRCMU-neutral, and calls will
be diverted to respective driver. Common registers are in
dbx500-prcmu-regs.h and common accessors and defines in
<linux/mfd/dbx500-prcmu.h> This way we get a a lot more
abstraction and code reuse.

This adds a header file that contains the set of functions and
definitions that will be shared between the DB8500 and DB5500
PRCMU drivers.
