gpu: nova-core: bindings: derive `MaybeZeroable`
Commit 4846300ba8f9 ("rust: derive `Zeroable` for all structs & unions
generated by bindgen where possible") automatically derives
`MaybeZeroable` for all bindings. This is better than selectively
deriving `Zeroable` as it ensures all types that can implement
`Zeroable` do.
Regenerate the nova-core bindings so they benefit from this, and remove
a now unneeded implementation of `Zeroable`.

gpu: nova-core: gsp: Retrieve GSP static info to gather GPU information
After GSP initialization is complete, retrieve the static configuration
information from GSP-RM. This information includes GPU name, capabilities,
memory configuration, and other properties. On some GPU variants, it is
also required to do this for initialization to complete.

gpu: nova-core: gsp: Add SetRegistry command
Add support for sending the SetRegistry command, which is critical to
GSP initialization.
The RM registry is serialized into a packed format and sent via the
command queue. For now only three parameters which are required to boot
GSP are hardcoded. In the future a kernel module parameter will be added
to enable other parameters to be added.
