mfd: Add support for remapping twl4030-power power states

The <RESOURCE>_REMAP register allows configuration of the <RESOURCE> in case
of a sleep or off transition.

Allow this property of resources to be configured (through twl4030_resconfig)
and add code to parse these values to program the registers accordingly.
