Subject: [PATCH v2 1/3] clk: qcom: dispcc-sm8650: 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.

It also changes dptx1_aux_clk_src to use the correct ops instead of
clk_dp_ops.

Fixes: 9e939f008338 ("clk: qcom: add the SM8650 Display Clock Controller driver")
