drm/sun4i: backend: Support alpha property on lowest plane
Unlike what we previously thought, only the per-pixel alpha is broken on
the lowest plane and the per-plane alpha isn't. Remove the check on the
alpha property being set on the lowest plane to reject a mode.
Fixes: dcf496a6a608 ("drm/sun4i: sun4i: Introduce a quirk for lowest plane alpha support")
