[Nouveau] [PATCH v2] nouveau/video: make sure that firmware is present when checking caps

Apparently some players are ill-prepared for us claiming that a decoder
exists only to have creating it fail, and express this poor preparation
with crashes (e.g. flash). Check that firmware is there to increase the
chances of there being a high correlation between reported capabilities
and ability to create a decoder.

Have to create a new channel on kepler, otherwise it doesn't work... Emil, I'm
keeping your tested-by since you tested the nv84_video bits which haven't
changed.
