From: Roman Stratiienko <roman.stratiienko@xxxxxxxxxxxxxxx>
According to DRM documentation the only difference between PRIMARY
and OVERLAY plane is that each CRTC must have PRIMARY plane and
OVERLAY are optional.
Allow PRIMARY plane to have dimension different from full-screen.
Fixes: 5bb5f5dafa1a ("drm/sun4i: Reorganize UI layer code in DE2")
Signed-off-by: Roman Stratiienko <roman.stratiienko@xxxxxxxxxxxxxxx>

v2:
- Split commit in 2 parts
- Add Fixes line to the commit message
v3:
- Address review comments of v2 + removed 3 local varibles
- Change 'Fixes' line
Since I've put more changes from my side, please review/sign again.
