drm/nouveau/fifo: turn all fifo modules into engine modules
Been tested on each major revision that's relevant here, but I'm sure there
are still bugs waiting to be ironed out.
This is a *very* invasive change.
There's a couple of pieces left that I don't like much (eg. other engines
using fifo_priv for the channel count), but that's an artefact of there
being a master channel list still. This is changing, slowly.
