[PATCH 08/18] regulator: stpmic1: fix registering missed regulators

[Marco Felsch]

The dts regulators subnode can be incomplete e.g. if the pre-programmed
values are valid and shouldn't be changed. Missing regulator nodes are
indicated by "of_regulator_match->of_node == NULL". Take missing
regulators into account and register only existing ones.
