b6466fbe07 gpu: nvgpu: add TSG support to runlists
- when a TSG channel is made runnable, add it to TSG's
  runnable list
- when a TSG channel is removed from runlist, remove it
  from TSG's runnable list

When we rewrite the entire runlist :
- first add all the channels which are not part of any TSG
- then find all active TSGs, add an entry in runlist for the TSG
  (with TSG id and length of TSG)
- then write entries for each channel in that TSG

28c35a1b99 gpu: nvgpu: Fault engines on PBDMA error
On PBDMA error even though the engine might not be wedged, we need to
kick the channel out of engine. Add that logic. Also when channel is
not in engine, we need to remove it from runlist.
