regulators: Fixed errors in ab8500 register mapping

For INTCORE and TVOUT regulators, the low power register bit is
included in the mask so that enable will set the regulator in
normal (high power) mode.

ANAMIC1, ANAMIC2, DMIC regulator settings are swapped with each
other so that the correct regulator gets enabled/disabled.

ANA regulator register address is corrected.
