twl6030: regulator: Configure STATE register instead of REMAP

to drive a resource to a given state.
The state register can be used to specify what state the resource should
enter when its associated with a GRP.

corresponding STATE registers for all LDO's to turn ON when assocaited
with GRP_P1.

P3_GRP |P2_GRP |P1_GRP |RES   |RES   |RES   |State1 |State0

State can be specified as below
00: OFF
