This is obviously just dumping the Linux driver model into the DT, the
regulators are clearly different.  If you want to explicitly list the
regulators in DT it'd be better to reflect the hardware and enumerate
the regulators individually - you can use one driver for all the MICVDDs
and a separate one for VDDCORE for example.
