  Add driver support for the RPM power domains found on the different
MSM8974 devices.

Devicetree integration will come at a later point since also some
mostly remoteproc drivers need to be adjusted.

Also the MX power domains on this SoC seems to work quite a bit
differently, we'd need to send raw voltages to it, so these are ignored
in this series.

I don't see a s4b_ao downstream.. Though it's very unfortunate we
didn't choose to add power-domain-cells or sth and set the bucket
through that..
