regulators/db8500: split off shared dbx500 code
As we progress with DB5500 and future voltage domain regulators based on very similar hardware as found in the DB8500 PRCMU, it makes sense to split off the generic parts and introduce some generic debug code for the DBx500 regulators. This patch accoplish a basic abstraction of the DBx500 voltage domain regulators.
