gpu: nvgpu: add API to recover TSG
- add and export API "gk20a_fifo_recover_tsg()" to
recover a TSG
- if TSG is running on any engine, then trigger MMU fault
on those engines
- otherwise, abort each channel in TSG
- modify channel specific API engines_on_ch() to generic
engines_on_id() which will take an ID and a flag to specify
whether ID is for channel or TSG and return engines running
on that ID
- modify channel specific API get_faulty_channel() to generic
get_faulty_id_type() which will take pointers to ID and type
of ID (either a regular channel or TSG)
- remove runlist update from recover_ch() since
no need to touch runlist during recovery
- set error notifier first and then only abort the channels
for TSG recovery path
- also, add necessary accessors to get engine
status type as TSG
