This patchset fixes corrupted display picture when primary plane isn't
full-screen.
Please review/merge.
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
v4:
Resend (author's email changed). Reword commit message.
Drop fixes line to allow more testing before back-porting.

Hi!
General note, you should send Allwinner specific patches to linux-
[email protected] too. It's already in MAINTAINERS, but probably it's not
yet propagated in all trees.

You should expand this a bit more. Most importantly why this fixes a bug? Rule
of thumb - if you used word "fix" in commit message, most of the time you
should add Fixes tag too.

CRTC variants are not appropriate here. These are adjusted for interlacing and
other stuff. This is important during TCON configuration, not here. Just drop
"crtc_" prefix.
