Long ago, there had been plans for making use of a bunch of these APIs
from userspace and there's various checks in place to stop misbehaving.
Countless other projects have occurred in the meantime, and the pieces
didn't finish falling into place for that to happen.
They will (hopefully) in the not-too-distant future, but it won't look
quite as insane. The super checks are causing problems right now, and
are going to be removed.

This switches to using the subdev list for lookup, and otherwise should
be a no-op aside from switching the function signatures.
Callers will be transitioned to split type+inst individually.

GA100 hidden behind a module option, as it's not been as well verified
since initial bring-up and may need additional changes.
There's no display anyway, so this can wait for a bit.

We have a need to fetch data from GPU-specific sub-devices that is not
tied to any particular engine object.
This commit provides the framework to support such queries.

MMU will be needing this to specify kind info on BAR mappings.
We have no userspace currently using these interfaces, so break the ABI
instead of supporting both. NVIF version bump so any future use can be
guarded.

In fact, both functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
So this patch marks these functions with 'static'.
