clk: qcom: gpucc-sa8775p: Park RCG's clk source at XO during disable

The RCG's clk src has to be parked at XO while disabling as per the
HW recommendation, hence use clk_rcg2_shared_ops to achieve the same.
Also gpu_cc_cb_clk is recommended to be kept always ON, hence use
clk_branch2_aon_ops to keep the clock always ON.
