gk20a_fifo_update_runlist_locked() and the vgpu counterpart do three
things:
1. find out whether there's a channel to add or remove (if not, the
whole runlist is just reconstructed or cleared),
2. reconstruct the runlist format for hardware (or the vgpu message),
3. actually update the runlist to hw and maybe wait for finish.
Split out the two first operations to separate functions to make the
code easier to understand. Now it's also clearer that the "add"
parameter behaves completely differently depending on whether the
channel pointer is NULL or not.
Also ignore (with a warning) channels not bound to a tsg. We shouldn't
get runlist updates on such channels. This simplifies the control flow a
bit.

A naked channel ID does not carry good information about the channel
validity and is a very low level construct for an API of this level.
Refactor the runlist updating fifo APIs to take a channel pointer.
While at it, delete the channel and wait_for_finish parameters from
gk20a_fifo_update_runlist_ids() - the only caller is suspend and resume
and the parameters were always null for channel and true for wait.

Split out native-specific engine info collection out of
nvgpu_init_runlist() so that it only contains common code. Call this
common function from vgpu code that ends up being identical.

Extract non-chip-specific code that manages the runlists (init, update,
reschedule etc.) to a new file in the common directory. Move the
declarations to a new matching runlist.h header.
