drm/nouveau: Fix TMDS on some DCB1.5 boards.
The TMDS output of an nv11 was being detected as LVDS, because it uses DCB type 2 for TMDS instead of type 4. Reported-by: Bertrand VIEILLE <Vieille.Bertrand@free.fr> Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
