Allow soc specific clk drivers to specify a custom reset operation. We
will use this in an upcoming patch to allow gpucc driver to specify a
differet reset operation for cx_gdsc.

Some clients like adreno gpu driver would like to ensure that its gdsc
is collapsed at hardware during a gpu reset sequence. This is because it
has a votable gdsc which could be ON due to a vote from another subsystem
like tz, hyp etc or due to an internal hardware signal. To allow
this, gpucc dr

through 'reset' framework for SC7280.
