Color dithering not working correctly because the graphics driver
assumes the panel support 8bpc, but the panel only supports 6bpc.

User reports the issue start appearing from v4.8-rc2.
The issue is fixed with the patch. 

Add a quirk to tell DRM that this panel only supports 6bpc.

[Regression Potential]
Low. This fix matches a very specific panel.
