No output to the panel. Definitely can be fixed, but current situation is that
we don't have anyone who has available time or device to tackle the problem.
I know it's not optimal, but on a way to achieve working mainline phones, my
thinking is better to mark it as broken in mainline until someone fixes
(assuming Fixes tag and backport) then just going black display (when we have at
least framebuffer now).
