Subject: [PATCH] drm/vc4: Add missing render node support

There shouldn't be any other driver support necessary, since none of
the driver-specific ioctls ever required auth, and none of them deal
with modesetting.

Indeed, somehow I thought you need to mark them all up explicitly. But
that's only the case for DRM_AUTH ioctls.

Aside: I wonder whether we should go through all the drivers and replace
DRM_AUTH | DRM_RENDER_ALLOW with 0? It looks a bit like drm ioctl flags
are cargo culted ...
