Alex Waterman 77c0b9ffdc gpu: nvgpu: Update runlist_update() to take runlist ptr
Update the nvgpu_runlist_update_for_channel() function:

  - Rename it to nvgpu_runlist_update()
  - Have it take a pointer to the runlist to update instead
    of a runlist ID. For the most part this makes the code
    better but there's a few places where it's worse (for
    now).

This starts the slow and painful process of moving away from
the non-runlist code using runlist IDs in many places it should
not.

Most of this patch is just fixing compilation problems with
the minor header updates.
