drm/amd/display: reset DSC clock in post unlock update
[why]
Switching between DSC clock or disable DSC block are not double buffered update.
Corruption is observed if these updates happen before DSC double buffered
disconnection.
[how]
Move DSC disable and refclk reset to post unlock update. Wait for DSC double buffered
disconnection and all mpccs are disconnected before reset DSC clock.
