Subject: [PATCH v2 00/14] Clean up RPM bus clocks remnants

After the recent cleanups ([1], [2]) some in-tree abusers that directly
accessed the RPM bus clocks, effectively circumventing and working
against the efforts of the interconnect framework, were found.

Patches 1-5 drop deprecated references and the rest attempt to stop
direct bus clock abuses.

Depends on [2].

8996 and 8998 remoteproc changes were not tested, they never worked on
my Sony phones.
