[PATCH v2] drm/amd/display: Add pixel encoding info to debugfs

[Rino André Johnsen]

Looked through the patch series from Andri Yngvason and that does
exactly what I wanted in the first place. I think that the patch
series should be encouraged to be merged in as fast as possible.

For the patch I have submitted, it stands on its own, since the patch
series from Andri Yngvason does not include anything in the debugfs.
This means whenever or not the patch series gets merged, at least
those with an AMD gpu can figure out which pixel encoding that is
used.
