This is intended to support named (with a handle, etc) objects having
children that don't have an outside reference.
This will replace the various hacks around the place where subdev
objects have children, and have to manually drop the self-refs so
that they can be destroyed etc when all the outside refs have gone.

We need to be able to process interrupts before the DRM code is able to
actually enable them, set it up ourselves. Also, it's less convoluted
to *not* use the DRM wrappers it appears...

It'd be pretty awesome if someone would care enough to port this all
properly to a class interface, perhaps submitting a command stream to
the core via a sw object on PFIFO (emulating how EVO works basically,
and also what nvidia have done forever..)..
But, this seems unlikely given how old this hardware is now, so, lets
just hide it away.
There's a heap of other bits and pieces laying around that are still
tangled. I'll (re)move them in pieces.

Seen in the wild, don't have the hardware but this hacks things up to
treat it the same as GF119 for now.
Should be relatively safe, I'd be very surprised if anything major
changed outside of PGRAPH. PGRAPH (3D etc) is disabled by default
however until it's confirmed working.

Compression not supported, and will be silently dropped. Original G80
can't handle this either and requires LINEAR memtype, though it's still
possible to correctly texture and m2mf to/from these objects anyway.

Not sure about the (gpc_nr == 1) condition, it's probably wrong but for
all the examples I've seen so far it matches what NVIDIA end up poking.

It's probably impossible to hit it now on mainline kernel.
I only noticed it because one of my debugging patches uses it.

Well it broke on my system too, so it was easy to fix.
I didn't even need gdm to trigger it!

This fixes regression caused by 1d7c71a3e2 (drm/nouveau/disp: port vblank handling to event interface),
which causes a oops in the following way:

If there are no channels, chan would never end up being NULL,
and so the null pointer check would fail.
Solve this by initializing chan to NULL, and iterating over temp instead.
Fixes oops when running intel-gpu-tools/tests/kms_flip, which attempts to
do some intel ioctl's on a nouveau device.
