Unless this is supposed to be applied by me?

BTW, I wonder why we need an rpm clk driver much at all nowadays, except
maybe for the XO clk state. The big user, from what I can tell, is the
interconnect driver and we don't use any of the features of the clk
framework besides the API to set a frequency. Maybe it would be better
to just push push the bus frequency logic into interconnect code, then
XO clk is the only thing we need to keep, and it can be a simple on/off
thing.
