Make recovery a more straightforward process. When we detect a fault,
trigger MMU fault, and wait for it to trigger, and complete recovery.
Also reset engines before aborting channel to ensure no stray sync
point increments can happen.

Synchronize gk20a and gm20b headers. All registers which were added
to gk20a are now added to gm20b, and some registers that are unused
are removed.

- 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
