This replaces the twisty, confusing, relationship between nvkm_event and
nvkm_notify with something much simpler, and less racey. It also places
events in the object tree hierarchy, which will allow a heap of the code
tracking events across allocation/teardown/suspend to be removed.
This commit just adds the new interfaces, and passes the owning subdev to
the event constructor to enable debug-tracing in the new code.
v2:

Userspace never ended up using this to be clever about dealing with
channel death, and it won't be, not like this anyway.

No longer required now that userspace can't touch anything that might
need it, and should fix DRM MM operations racing with each other, and
the random hangs/crashes that come with that.

up instead.

The namespace of NVKM is being changed to nvkm_ instead of nouveau_,
which will be used for the DRM part of the driver. This is being
done in order to make it very clear as to what part of the driver a
given symbol belongs to, and as a minor step towards splitting the
DRM driver out to be able to stand on its own (for virt).
Because there's already a large amount of churn here anyway, this is
as good a time as any to also switch to NVIDIA's device and chipset
naming to ease collaboration with them.
A comparison of objdump disassemblies proves no code changes.
