[ Upstream commit 4b057462bb61a6571608ba393e6e018c9da9c9c3 ]

Use shared_floor_ops for the SDCC RCGs so the RCG is safely parked
during disable and the new parent configuration is programmed in
hardware only when the new parent is enabled, avoiding cases where
the RCG configuration fails to update.

Fixes: 108cdc09b2de ("clk: qcom: Add GCC driver support for SDX75")
