GSP boot needs a stable view of vGPU state before it starts building the
boot-time data structures that depend on SR-IOV and firmware policy. That
state must be derived once from the PCI VF count and the FSP PRC vGPU mode
knob before booting GSP.

Add VgpuManager to detect and retain the vGPU state during GPU
construction. Keep the manager separate from the detected state because
later vGPU milestones will add vGPU resources and lifecycle state to it.

Keep the vGPU capability gate local to the vGPU module with per-chip HAL
modules. Treat failures to detect the optional vGPU state as disabled so
they do not prevent a bare-metal probe, and log both the failure and the
detected state where the manager is constructed.

Currently the lifetime on `Core` and `CoreInternal` is covariant. This
means that they can be coerced into shorter living lifetimes. On `probe`
function, signature has `&'bound Device<Core<'a>>`; the type's wellformness
would imply `'a: 'bound` and thus the type can be coerced `&'bound
Device<Core<'bound>>`, defeating the purpose of having the lifetime bound
to prevent users of the `Core` type to escape the function.

Fix this by making the lifetime invariant, so the coercion is impossible.
The lifetime here only needs to be "branded" so it does not coerce or unify
with other lifetimes, so we do not need to ensure `'bound: 'a`.

This requires modifying `nova-core` which relies on this implied bound due
to pre-2024 capture rule. The "use" bound can be removed if built with
edition 2024.

[ Fixup the debugfs sample to use an explicit lifetime instead of
  Core<'_>. - Danilo ]
Signed-off-by: Danilo Krummrich <dakr@kernel.org>

The `Fsp` instance was only used in the Hopper+ boot path, and
consequently built locally (and immediately dropped) in it.

This worked well as a temporary measure, but the FSP is a GPU
sub-device, so its lifetime should match the GPU rather than a single
boot invocation.

It will also be needed in other parts of the driver, for instance vGPU.

Thus, create the `Fsp` instance in the `Gpu` constructor and store it
there, passing it to the GSP boot as a mutable reference using
`GspBootContext`. This makes the `Fsp` available even after the GSP is
booted.

The files to give the `ModInfoBuilder` depend on the chipset; this is
HAL information, so move it there. Doing so lets us remove the
`uses_fsp` and `needs_fwsec_bootloader` ad-hoc methods of `Chipset`.

`GspBootContext` contains the resources required to boot the GSP. As it
turns out, this is also the context required for unloading it.

Reflect that fact by replacing the arguments of `Gsp::unload` and
`UnloadBundle::run` with the `GspBootContext`. This symmetry between
`Gsp::boot` and `Gsp::unload` will also be convenient when we want to
make these methods generic over the boot context corresponding to the
boot method used.

Store the bound device and `BAR0` mapping in `Falcon` instead of passing
them through every `Falcon` operation. This simplifies the `Falcon` API and
removes repeated `dev`/`bar` plumbing from reset, load, boot, mailbox, DMA,
and GSP/FSP-specific Falcon helpers.

`FalconHal` now receives a reference to a `Falcon` and uses its methods and
members instead of passing them individually.

Add usable_fb_regions() to GspStaticConfigInfo to extract the usable FB
regions from GSP's fbRegionInfoParams. Usable regions are those that are
not reserved or protected.

The extracted regions are stored in GetGspStaticInfoReply and exposed
for use by the memory subsystem.

Display the regions and their total size upon device probe.

The GSP static information is useful during regular driver runtime;
however it is currently obtained from `Gsp::boot`, with no elegant way
to pass it back to the caller.

Solve this by moving the code acquiring it to a dedicated method of
`Gsp` that can be called as soon as the `Gsp` is booted. This allows us
to obtain and display the static information from the `Gpu` constructor,
and to store the static information for later use.

Its location at the end of `Gsp::boot` was a bit out-of-place anyway:
technically, the GSP is considered booted after we have received the
`GspInitDone` message, so anything that happens afterwards is not part
of the boot sequence anymore.
