regulator: twl: remap has no meaning for 6030
TWL6030 does not have remap register. The current implementation
causes value of remap to be written to state register, accidentally
causing the regulators which are probed to be switched on as well.
This is wrong as regulators should be controllable based on calls
to enable/disable for TWL regulator framework. Further, the values
initialized make no sense as well. We hence remove this from the
initalizers and also write to remap register only if the TWL
is 4030.
