Today's -next fails to build an arm64 defconfig due to:

DRM_SUN4I unconditionally uses these symbols which are only defined when
DRM_SUN8I_TOP is enabled, not sure what the exact cause is but there's a
few recent patches to that driver from Jonathan and Chen-Yu so CCing for
that.  I've been missing arm64 builds for a little while so this
could've been there before today.

Patch seems to have been stuck on dri-devel. I smashed an r-b onto it
so Maxime can apply. Plus a mild rant about Kconfig combinatorial
explosion and whether that's really, really worth all the trouble it's
causing, because I couldn't help myself :-)
