[PATCH v2] drm/nouveau: use nv_debug for NV_DEBUG, make DRM a separate subflag

[Ilia Mirkin]

It's really confusing for NV_DEBUG's printing to be controlled via
drm.debug while everything else is controlled via nouveau.debug. These
messages can be turned on with nouveau.debug=DRM=debug.

Updated version that makes the top-level DRM client have a separate debug flag
from everything else, since it presents debug info that's interesting for a
very different set of use-cases.
