power: regulator: palmas: fix ldoln and ldousb detection
dev->driver_data will carry the tail of ldo if there is a number and
if there is no number it will be an error code, anyway it will not be
zero. This results in a wrong ldo regulator detection.
To avoid this check for non-numerical ldo first and then manipulate
dev->driver_data.
