Update the SDCC clock RCG ops to floor_ops to avoid overclocking issues

Split, please.


Sure, will split this patch in next series.

and remaining RCGs to shared_ops to park them at safe clock(XO) during
disable.

Why are you doing this, is there any issue? Previously we had only a several clocks implemented this way, which were really shared with other subsystems (this is the where name _shared_ops comes from).


From our clock hardware side, the expectation is to park the RCGs at XO for most of the clocks and the shared_ops is the closest implementation for the same. Hence updating the RCG ops to clk_rcg2_shared_ops.

Thanks,
Imran
