regulator: ab8500: Test dedicated enable bits only
Some regulator control registers have independent enable and low-power
bits. is_enabled() currently tests their combined update mask, so an
off regulator with its low-power bit set is incorrectly reported as
enabled.
Add an optional enable mask and use it for VINTCORE, AB8500 TVOUT,
AB8505 ADC, and AB8505 VAUX5/6. Regulators whose two-bit field encodes
the complete operating state continue to test the full update mask.
