[ Upstream commit 0e190a0446ec517666dab4691b296a9b758e590f ]
Scaling doesn't work on DCE6 at the moment, the current
register programming produces incorrect output when using
fractional scaling (between 100-200%) on resolutions higher
than 1080p.
Disable it until we figure out how to program it properly.
Fixes: 7c15fd86aaec ("drm/amd/display: dc/dce: add initial DCE6 support (v10)")
