632644b44a gpu: nvgpu: couple runlist domains and nvs
Now that the main nvsched code exists in the nvgpu build, make it
control the runlist domains. As a new nvs domain is created, create the
relevant runlist data too. To support the default domain, create a
default nvs domain at boot.

The scheduling domain code owns the responsibility of domain lifetime,
and runlist domains exist to serve that logic although the RL domains
are directly used by channel and TSG logic. Add refcounting to the
scheduler uapi level to make sure that busy domains (that still have TSG
participants) do not get removed too early.

Adjust error injection sensitive unit tests to match the updated logic.

1d14a4412f gpu: nvgpu: scheduler management uapi
Add ioctls for creating, removing and querying scheduling domains and
interface with the "nvsched" entity that will be the core scheduler.
Include the scheduler in the Linux build.

The core scheduler code will ultimately hold data on and control what
gets scheduled, but this intermediate layer in nvgpu-rm needs a bit of
bookeeping to manage the userspace interface.

To keep changes isolated, this does not touch the internal runlist
domains yet. The core scheduler logic will eventually control the
runlist domains.
