gpu: nvgpu: gr faults: do not depend on fake mmu fault notifier

Browse Source 
Currently NVGPU_CHANNEL_FIFO_ERROR_MMU_ERR_FLT is being set in
error notifier for non mmu fault too. For fake mmu faults i.e.
trigger mmu fault cases, make sure proper notifiers are set and
driver is not depending on sending mmu error fault notifier.
This change is needed for t19x fifo recovery too.

NVGPU_CHANNEL_GR_ERROR_SW_METHOD (12), NVGPU_CHANNEL_GR_EXCEPTION(13)
and NVGPU_CHANNEL_FECS_ERR_UNIMP_FIRMWARE_METHOD (37) are new error
notifiers.
