regulator: core: don't call of_regulator_get with NULL argument
regulator_get calls either of_regulator_get or dev_regulator_get, both
of which accept a supply parameter. Only dev_regulator_get gracefully
handles a NULL supply by considering all registered regulators.
of_regulator_get on the other hand, will complain at debug level,
before returning NULL:
uart-pl011 fe201000.serial@7e201000.of: No <NULL>-supply node found,
using dummy regulator
Avoid this message by skipping of_regulator_get if no supply was found
and directly call dev_regulator_get.
