gpu: nvgpu: fix GV100 hal definitions

These changes allow GV100 to init the basic HALs to pass
nvgpu_submit_twod

(1) Allocate fault buffer from vidmem instead of sysmem to prevent coherency
issues
(2) Properly enable FB
(3) Fan control requires the execution of the pre-os FW, without it the SKU201
is extremely noisy
