e4a7bc1602 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
