6.6-stable review patch.  If anyone has any objections, please let me know.

From: Val Packett <redacted>

[ Upstream commit 8c522da70f0c2e5148c4c13ccb1c64cca57a6fdb ]

mdss_gdsc can get stuck on boot due to RCGs being left on from last boot.
As a fix, commit 01a0a6cc8cfd ("clk: qcom: Park shared RCGs upon
registration") introduced a callback to ensure the RCG is off upon init.
However, the fix depends on all shared RCGs being marked as such in code.

For SM8150/SC8180X/SM8250 the MDSS vsync clock was using regular ops,
unlike the same clock in the SC7180 code. This was causing display to
frequently fail to initialize after rebooting on the Surface Pro X.
Fix by using shared ops for this clock.
