Subject: [PATCH AUTOSEL 4.18 131/136] drm/vc4: Add missing formats to
 vc4_format_mod_supported().

From: Eric Anholt <eric@...olt.net>

[ Upstream commit 1e871d65e375280757833d9fce91dda71980bdf5 ]

Daniel's format_mod_supported() patch predated Dave's for NV21/61, and
I didn't catch that when rebasing.  This is a problem since the
formats are now getting validated before being passed to the driver's
atomic hooks.
