Saving the current UVD state on suspend and restoring it on resume
just doesn't work reliable. Just close cleanup all sessions on suspend.

Support for output_csc is only available on DCE5 and newer so
don't mess with the HDMI quantization_range on pre-DCE5 asics.

Rather large pull request this time around, due to the long-pending
cleanup of the kernel driver being here.  There's a stupidly large
number of commits for that, as I wanted to have the series be
bisectable at a fairly fine-grained level.  That said, a very large
portion of the churn in the rework was automated, and a very large
number of boards from right across the whole range we support have
been tested.  I'm fairly confident there shouldn't be (too many)
issues from this.

Beyond correcting some not-so-great design decisions and making the
code a lot easier to work with, there's not much exciting (lower
memory usage, GPU VM should be a lot faster, etc) to be gained by the
end-user as a result of the cleanup, it mostly lays the groundwork for
future improvements.

A big thanks goes to Alexandre Courbot for testing/debugging the GK20A
codepaths for me :)

Highlights:
- A heap of perfmon work, providing a more useful userspace interface
and specifying counters for a bunch of boards
- Support for GT200 reclocking + other misc pm improvements
- Initial patches towards supporting GM20B (Tegra X1)
- Maxwell DisplayPort fixes
- Cleanup of the kernel driver
- The usual collection of random fixes

The copyright header in nvkm/engine/device/platform.c has been replaced
with the NVIDIA one from drm/nouveau_platform.c, as most of the actual

This ensures we have a valid mask of disabled engines before we start
trying to execute fini()/init() on the subdevs, potentially touching
