Remain consistent with existing naming
Use the TWL4030_PM_RECEIVER prefix

Are you sure, you want to do this

VMMC1_VSEL_30

Changed to

TWL4030_PM_RECEIVER_VMMC1_VSEL_30

It looks very awkward to me, More over the prefix is used for register
definition already. This is bit value - Kindly confirm

Khasim
