drm/amd/display: Disable scaling on DCE6 for now

Browse Source 
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: 7c15fd86aa ("drm/amd/display: dc/dce: add initial DCE6 support (v10)")
