2025-05-19drm/nouveau/gv100-: switch to volta semaphore methodsBen Skeggs
HOPPER_CHANNEL_GPFIFO_A removes the SEMAPHORE[A-D] methods that are currently used by nouveau to implement fences on GF100 and newer. Switch to the newer SEM methods available from VOLTA_CHANNEL_GPFIFO, which are also available on the Hopper/Blackwell host classes.
