eic7700 pin configuration nodes act as a container for an arbitrary number of
subnodes. Each of these subnodes represents some desired configuration for one or
more pins. This configuration can include the mux function to select on those pin(s),
and various pin configuration parameters, such as input-enable, pull-up, etc.

Regulator supply for the RGMII interface IO power domain.
This property should reference a regulator that provides either 1.8V or 3.3V,
