Seema Khowala 5cda5a3074 gpu: nvgpu: gv11b: add a function to reset pbdma and eng faulted ...

When Host receives a page fault signal from a CE, Host will immediately
set _ENG_FAULTED bit in the NV_PCCSR_CHANNEL register for the channel
and will trigger a preempt of the TSG/channel.
A channel will only be scheduled when _ENABLED=1, _ENG_FAULTED=0
and _PBDMA_FAULTED=0 in pccsr_channel reg for the channel.
If a TSG has a faulted channel, Host will not schedule the entire TSG
agin until all _FAULTED bits from channels in the TSG are cleared by SW.
This function will be required for ce page fault handling.
