regulator: lp873x: Add support for populating input supply

Browse source 
In order to have a proper topology of regulators for a platform, each
registering regulator needs to populate supply_name field for identifying
its supply's name. Add supply_name field for lp873x regulators.

- #gpio-cells: Should be two. The first cell is the pin number and
the second cell is used to specify flags.
See ../gpio/gpio.txt for more information.
- xxx-in-supply: Phandle to parent supply node of each regulator
populated under regulators node. xxx can be
buck0, buck1, ldo0 or ldo1.

initialization data.
