Nikola Cornij a5132f9728 drm/amd/display: Add a sanity check for DSC already enabled/disabled ... [why] If acquire/release DSC resource sequence is affected by a regression, it can happen that the already-in-use DSC HW block is being wrongly re-used for a different pipe. The reverse is also possible, i.e. already-disabled DSC HW block could be disabled from other context. [how] Read back the enable state of DSC HW and report an error if duplicate enable or disable was attempted.
