Subject: [PATCH 0/4] gpu: nova-core: Fixups for GSP message queue and
 bindings

This series contains a few fixups for the recently merged GSP
command-queue code, by order of importance:

- Some explicit padding required to safely implement `AsBytes` was
  missing in the bindings,
- A bug in the received message length calculation results in the
  message handler being given more data than it should, 
- `MaybeZeroable` is now derived by the kernel's bindgen, but the Nova
  bindings have not been updated for that,
- Some items in the bindings were referred to using the version module
  directly, instead of the alias we defined to limit the diff when we
  upgrade firmware versions.

All of them address "bugs" (with the first two fixing actual correctness
issues), but since Nova does not do much anyway, they are also not
absolutely critical and can wait -rc1 if we prefer to do so.
