mach-ux500: voltage domain regulators for DB8500

From: Bengt Jonsson <[email protected]>

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.

though I would prefer to see the regulator driver in drivers/regulator (though splitting the underlying integration with cpuidle isn't a problem) as this makes it easier to find all regulator drivers.
