Thomas Zimmermann 746b9c62cc drm/gem: Ignore color planes that are unused by framebuffer format
Only handle color planes that exist in a framebuffer's color format.
Ignore non-existing planes.

So far, several helpers assumed that all 4 planes are available and
silently ignored non-existing planes. This lead to subtil bugs with
uninitialized data in instances of struct iosys_map. [1]
