[PATCH 00/27] gpu: nova-core: boot on the r000 GSP firmware

Nova-core boots the 570.144 GSP firmware today. This series moves the
driver to the r000 firmware ABI, which is stable across releases, so
firmware file names no longer carry a version number.

The actual firmware is not yet publicly available, so this series is for
early review, and should not be merged until the corresponding firmware
shows up.

Beyond drm-rust-next, the series sits on these patchsets:

* The GIN interrupt controller series, which needs Danilo Krummrich's
  PCI and irq rework and Joel Fernandes' wait_for_completion_timeout().

* Eliot Courtney's NVKV encoder and decoder, which GSP_INIT is built on,
  and his Vec::push_init.

I've created a branch that has everything, for reviewer convenience,
here:

  https://github.com/johnhubbard/linux/tree/nova-core-run-on-r615-or-later-v1

Patch 25 makes the big switch from r570 to r000 in one commit. Before
that commit, everything works on r570. After that commit, only r000 is
supported. Patches 1 to 24 add the pieces the switch needs, and patches
26 and 27 delete and clean up after it.

Tested on TU117 (Turing, T400), GA104 (Ampere, RTX A4000) and GB202
(Blackwell, RTX PRO 6000), covering PCIe probe, chipset and GPU name
readback, the interrupt delivery self-test, and the KUnit suites.

Also, the vGPU team has tested an earlier, nearly identical version of
this patchset (minus the cleanups at the end), and it works there too.
