drm/nouveau/nvkm: punt spurious irq messages to debug level
This can be completely normal in some situations (ie. non-stall intrs
when nothing is waiting on them).

drm/nouveau/intr: add nvkm_subdev_intr() compatibility
It's quite a lot of tedious and error-prone work to switch over all the
subdevs at once, so allow an nvkm_intr to request new-style handlers to
be created that wrap the existing interfaces.
This will allow a more gradual transition.

drm/nouveau/intr: support multiple trees, and explicit interfaces
Turing adds a second top-level interrupt tree in HW, in addition to the
trees available via NV_PMC. Most of the interrupts we care about are
exposed in both trees, but not all of them, and we have some rather
nasty hacks to route the fault buffer interrupts.
Ampere removes the NV_PMC trees entirely.
Here we add some infrastructure to be able to handle all of this more
cleanly, as well as providing more explicit control over handlers.

drm/nouveau/nvkm: give each nvkm_event its own lockdep class
The vblank and nonstall events have some annoying interactions with DRM
locking, and aren't able to do certain things as a result.
However, other uses of event notifications don't have such requirements,
and upcoming patches take advantage of this for various improvements.
Having separate classes for each nvkm_event's spinlocks allows lockdep
to distinguish between them and avoid false-positives.
