rpm-smd-regulator devices.  This ensures that requests made for
these regulators are aggregated by the RPM processor along with
the requests from other processors.

device
-SMPS 1 of mdmfermium should not be converted to rpm-smd-regulator
because it is used and controlled by APC CPR regulator device.
