drm/amd/display: Add work around for tunneled MST.
[Why] Certain USB4 docks do not seem to be able to handle disabling DSC once it has been enabled on an MST stream. This can result in blank displays. [How] As a work around, always enable DSC on docks exhibiting this issue. The flag to indicate the use of DSC for MST streams on a USB4 dock is set during detection of the dock and only cleared when the USB4 dock is disconnected.
