[PATCH] drm/imx: lift 64x64 pixel minimum framebuffer size requirement

[PATCH] drm/imx: lift 64x64 pixel minimum framebuffer size requirement

[Philipp Zabel]

There is no reason to limit framebuffer size to 64x64 pixels at a
minimum on creation. The actual scanout limitations (width >= 13 for the
base plane and height >= 2) are checked in atomic_check.
