[PATCH v2] clk: qcom: gcc: Update the SDCC clock to use shared_floor_ops

[PATCH v2] clk: qcom: gcc: Update the SDCC clock to use shared_floor_ops

[Taniya Das]

Fix "gcc_sdcc2_apps_clk_src: rcg didn't update its configuration" during
boot. This happens due to the floor_ops tries to update the rcg
configuration even if the clock is not enabled.
The shared_floor_ops ensures that the RCG is safely parked and the new
parent configuration is cached in the parked_cfg when the clock is off.

Ensure to use the ops for the other SDCC clock instances as well.

Fixes: 39d6dcf67fe9 ("clk: qcom: gcc: Add support for QCS615 GCC clocks")

:(

The subject also needs to be 'gcc': -> 'gcc-qcs615:'
