clk: qcom: mmcc-msm8974: use clk_rcg2_shared_ops for mdp_clk_src clock
[ Upstream commit 8fd492e77ff71f68f7311c22f7bc960182465cd7 ]
The mdp_clk_src clock should not be turned off. Instead it should be
'parked' to the XO, as most of other mdp_clk_src clocks. Fix that by
using the clk_rcg2_shared_ops.
