Thanks for the suggestion! No worries, this is such a strange/weird
problem, that basically any idea has merit at this point.

I tried increasing the CMA area from 256M -> 512M, but there was no
impact. The critical framebuffer width still remains the same
(=0x900).

And everything works fine on a classic i.MX6Quad, it's only the
i.MX6QuadPlus that has the problem. I am running i.MX6Quad and
i.MX6QuadPlus side-by-side with identical kernels/rootfses. Obviously
the devicetree is slightly different.
