[SRU] [Artful] [PATCH 0/1] Fix color dithering for Asus UX303LA

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1749420

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

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

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

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