drm/nouveau: add support for GB20x

This commit adds support for the GB20x GPUs found on GeForce RTX 50xx
series boards.

Beyond a few miscellaneous register moves and HW class ID plumbing,
this reuses most of the code added to support GH100/GB10x.

drm/nouveau: add support for GH100

This commit enables basic support for Hopper GPUs, and is intended
primarily as a base supporting Blackwell GPUs, which reuse most of
the code added here.

Advanced features such as Confidential Compute are not supported.

Beyond a few miscellaneous register moves and HW class ID plumbing,
the bulk of the changes implemented here are to support the GSP-RM
boot sequence used on Hopper/Blackwell GPUs, as well as a new page
table layout.

There should be no changes here that impact prior GPUs.
