regulator: initialization for ab8500 regulators

The regulators on the AB8500 have a lot of custom
hardware control settings pertaining to 8 external
signals, settings which are board-specific and need
be provided from the platform at startup.

Initialization added for regulators Vana, VextSupply1,
VextSupply2, VextSupply3, Vaux1, Vaux2, Vaux3, VTVout,
Vintcore12, Vaudio, Vdmic, Vamic1, Vamic2, VrefDDR.
