nouveau/video: mark bitstream-level acceleration as unsupported

Adding a vl_mpeg-based helper didn't seem to work, as it produced data
that the card couldn't handle. (And I didn't investigate further.) This
makes the decoding functionality only accessible via XvMC and avoids
crashes when attempting to use VDPAU.
