[PATCH 2/2] regulator: palmas: add input supply names

[Laxman Dewangan <ldewangan@nvidia.com>]

Palmas regulator support the different input supply pins for each of
the rails. Fill the regulator info data with their input supply pin
names.

The pin supply names is passed to regulator_register() only when there
is valid regulator_init_data. If regulator_init_data is not present
for the rail then it is assumed that given rail's input pin is left
unconnected.
