[PATCH] drm: enable render-nodes by default

We introduced render-nodes about 1/2 year ago and no problems showed up.
Remove the drm_rnodes argument and enable them by default now.

Hi Dave

This does _not_ depend on the "drm-minor" branch. We decided to not provide
reliable minor-numbers. User-space should just properly enumerate devices
instead of relying on some minor-math-magic. Furthermore, so far no-one
complained about any render-node issues, so I don't think there's any reason to
keep them experimential.

Thanks
David
