[PATCH V2] regulator: palmas: add input supply names

[Laxman Dewangan]

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

Signed-off-by: Laxman Dewangan <ldewangan@xxxxxxxxxx>

Changes from V1:
- Passing desc->sname for input supply unconditionally.
- If input pins are unconnected then it will be connect
  to floating supply.
