gpu: nvgpu: Add HALs for mmu_fault setup and info

Add below HALs to setup mmu_fault configuration registers and to read
information registers and set them on Volta

gops.fb.write_mmu_fault_buffer_lo_hi()
gops.fb.write_mmu_fault_buffer_get()
gops.fb.write_mmu_fault_buffer_size()
gops.fb.write_mmu_fault_status()
gops.fb.read_mmu_fault_buffer_get()
gops.fb.read_mmu_fault_buffer_put()
gops.fb.read_mmu_fault_buffer_size()
gops.fb.read_mmu_fault_addr_lo_hi()
gops.fb.read_mmu_fault_inst_lo_hi()
gops.fb.read_mmu_fault_info()
gops.fb.read_mmu_fault_status()
