Subject: [PATCH] clk: qcom: gcc: Update the SDCC clock to use
shared_floor_ops
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 new parent configuration is
cached in the parked_cfg in the case where 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")
