- Use driver level (0x2) for NV_DEBUG instead of all levels
- Create a NV_DEBUG_KMS for KMS level (0x4) and use them in modesetting code
- Remove a few odd NV_TRACE calls and replace some of them with NV_DEBUG_KMS or
NV_INFO

This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA.

This driver is a KMS-based driver and requires a compatible nouveau
userspace libdrm and nouveau X.org driver.

This driver requires firmware files not available in this kernel tree,
interested parties can find them via the nouveau project git archive.

This driver is reverse engineered, and is in no way supported by nVidia.

Support for nearly the complete range of nvidia hw from nv04->g80 (nv50)
is available, and the kms driver should support driving nearly all
output types (displayport is under development still) along with supporting
suspend/resume.

This work is all from the upstream nouveau project found at
nouveau.freedesktop.org.
