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.

Applied for next, thanks!
Note that patch1 is also available at the immutable dt branch, if soc
maintainers need to pull it in too.
Kind regards
