Philippe CORNU aefa830199 drm/stm: ltdc: add non-alpha color formats
ltdc supports natively some color formats with alpha (like
ARGB8888, ARGB1555, ARGB4444...). Related non-alpha formats are
supported too (ARGB8888->XRGB8888, ARGB4444->XRGB4444...) by
adjusting ltdc blending factors.

Note: Wayland/Weston requests by default the non-alpha XRGB8888
color format.
