regulator: ab8500: Clean out SoC registers

Clean out initialization that is handled by SoC.
Regulator settings for Vpll (partly), Vsmps1,
Vsmps2, Vsmps3 (partly), Vrf1, Varm, Vape, Vbb,
Vmod are cleaned out. They should not be touched
by the kernel.

This patch removes the possibility to set these
register bits as well (change in the driver). If
there is a need to set these bits, they should be
set during early boot, in e. g. SoC settings.
