[PATCH v3 0/8] gpu: nova-core: miscellaneous improvements

[Alexandre Courbot]

A few simple, loosely-related small improvements for nova-core,
including reporting unprocessed data in GSP messages, removal of
unnecessary code in GSP and the sequencer, and leveraging the Zeroable
derive macro and core library's CStr. Probably nothing too
controversial, so I plan on applying it soon after -rc1 gets released.

This revision is based on master.

Changes in v3:
- Use inspect() to warn about remaining data in the GSP command queue.
- Drop "firmware: fwsec: do not require bound device when unneeded".
- Drop "simplify str_from_null_terminated" as `str_from_null_terminated`
  has been removed.
- Derive `Zeroable` on the original `GspStaticConfigInfo` tuple struct.
- Link to v2: https://patch.msgid.link/20251216-nova-misc-v2-0-dc7b42586c04@xxxxxxxxxx

Changes in v2:
- Rebase on drm-rust-next.
- Add a patch to reuse previously acquired reference to define in GSP
  boot sequence.
