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.
