[PATCH v1 resend] regulator: new driver for LP8755
This driver is a general version for lp8755 regulator driver of TI.
LP8755 :
The LP8755 is a high performance power management unit.It contains
six step-down DC-DC converters which can can be filexibly bundled
together in multiphase converters as required by application.
