They instantiate regulators. The bcm590xx binding specifies the
allowable subnode names permitted here. This replaces the old method
of specifying an index or the deprecated regulator-compatible property.
The board-specific dts includes this dtsi and applies any board
constraints to a subset of regulators that need them. Unused regulators
are all disabled which is what we want.

Not necessary for these subnodes.
