Hmm, well, on the HW they are different. We have CRTC limits, and we
have plane limits.

In our HW, I think we can have 1x1 planes (at least with RGB). But CRTC
minimum depends on the display used. In some cases CRTC minimum is 1x1,
but usually it's 8x1 I think.

And talking about primary or overlay planes is so legacy... With atomic,
we just have planes! =)
