Revert "drm: Avoid circular dependencies for CONFIG_FB"

This reverts commit f611b1e.

1/ When initially starting planes loop, everything looks fine. After a
few minutes/few iterations, things begin to go very bad. The chicken and
the martian look good, but after a few minutes, they turn upside down.

2/ More than this, after a few minutes, the image begins to crumble, it
goes bad, flickering appears as in very bad pixels, It looks like big
de-synchronization of the pixels with the clock... I have no idea.

3/ I have replaced linux-5.15-mchp with current linux-5.10-at91 , same
rootfs, same egt, no other change. Everything looks perfect, no flipped
overlays, no crumbling of the image, nothing. Hence I assume kernel is
the culprit here, and there is no problem with the screen, the ribbon or
anything hardware related.
