drm/amd/display: DSC Clock enable debugfs write entry

Browse Source 
[Why]
Need a mechanism to force enable DSC on any connector

[How]
Debugfs entry overwrites newly added connector's dsc preffered
settings structure and sets dsc_clock_en flag on it.
During the attomic commit, depending if connector is SST or
MST, we will enable DSC manually by overwriting stream's DSC flag.
