Bengt Jonsson 1032fbfd79 mach-ux500: voltage domain regulators for DB8500
The DB8500 has ePOD:s (electronic power domains) which are possible
to switch on/off to deactivate silicon blocks on the DB8500 SoC
by cutting their power without retention. We model these as simple
regulators with one bit on/off settings.
