Merge branch '00.06-gr-ampere' of https://gitlab.freedesktop.org/skeggsb/nouveau into drm-next

This is the pull request for a whole bunch of fixes and prep-work that
was done to support Ampere acceleration prior to GSP-RM being
available.  It uses the ACR firmware released by NVIDIA in
linux-firmware, as we do on earlier GPUs.  The work to support running
on top of GSP-RM also heavily depends on various pieces of this
series.

In addition to the new HW support, general stability of the driver
should be improved, especially around recovering HW from bugs that can
be generated by userspace driver components.
