This is no REMAP register on twl6030, instead there is a STATE register
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.
Register Bit field description is as below. The patch programmes the
corresponding STATE registers for all LDO's to turn ON when assocaited
with GRP_P1.

STATE REG:
Bit7 |Bit6 |Bit5 |Bit4 |Bit3 |Bit2 |Bit1 |Bit0
P3_GRP |P2_GRP |P1_GRP |RES |RES |RES |State1 |State0

State can be specified as below
00: OFF
01: ON
10: OFF
11: SLEEP
