Using this may be hazardous---we don't know if some of the GPU drivers
use this after initial bring-up. If they do, and we race with them in
setting it, or we unexpectedly change it under them, arbitrary state
corruption could occur.
This is only entirely safe to use if you don't trust the GPU state
after the first use of this fallback. In limited experiments vs the
`nvgpu` (Tegra) and `nvidia` (closed-source discrete) drivers, no
ill side effects have yet been observed, but still please use with
caution.

Also check for read success in get_runlist_iter().

Adds:
- /proc/preempt_tsg which takes a TSG ID
- /proc/disable_channel which takes a channel ID
- /proc/enable_channel which takes a channel ID
- /proc/switch_to_tsg which takes a TSG ID
Also significantly expands documentation and structs available in
nvdebug.h.

- The sequence file infrastructure prior to kernel version 4.19
has a bug in the retry code when the write buffer overflows that
causes our private iterator state to be corrupted. Work around
this by tracking some info out-of-band.
- Now supports including detailed channel status information from
channel RAM when printing the runlist.
- Adds helper function to probe for and return struct gk20a*.

`cat /proc/runlist` to print the current runlist.
Also break nvdebug.c into nvdebug_entry.c, runlist.c, and
runlist_procfs.c.
