`GspBootContext` contains all the resources currently carried by
`GspSequencerParams`, so replace the latter with the former for better
integration with the boot process and less code.

The sequence is currently stored in the `GspSequencer` even though its
lifetime is limited to `GspSequencer::run`. This object-oriented design
does not play well with the borrow-checker, as `GspSequencer::iter`
borrows a reference to the `GspSequencer`, which makes it difficult to
introduce mutable references in `GspBootContext`, as we want to do in
order to make the `Falcon` references mutable.
Thus, store the sequence locally in `GspSequencer::run`, and move
iterator creation to `GspSeqIter::new` so it no longer needs to borrow
the whole `GspSequencer`.

The next patch aims at replacing the cumbersome `BootUnloadGuard` with a
more local and less intrusive mechanism to run the GSP unload sequence
upon GSP boot failure. Doing so requires running the boot code in a
local closure, which changes its indentation and would make other
changes difficult to track in the diff. Thus, this preparatory patch
moves said boot code into a local closure that is run upon construction,
so the next patch does not need to re-indent code that changes.
This is a mechanical preparatory patch to make the next patch easier to
read. No functional change intended.

When adding the GSP unload capability, we introduced new types to
support what is effectively an ad-hoc behavior: that `Gsp::unload` must
be run if any error occurs during the boot sequence.
Furthermore, `BootUnloadGuard` is problematic because it holds
additional references to the boot context, notably the `Falcon`s. These
extra references stand in the way of making some of the `Falcon`'s
methods mutable, since those methods would require exclusive access. As
this behavior is only needed in one place, introducing dedicated types
for it is distracting and unnecessary.
Thus, take advantage of the local closures introduced in the preceding
patch to run the unload sequence in `Gsp::boot` if an error occurred at
any step of the boot process.
This slightly broadens the failure cleanup path, as `Gsp::boot` now
attempts a best-effort `Gsp::unload` even when the failure happened
before the unload bundle was prepared.

The warning emitted when the unload bundle cannot be constructed is valid
regardless of the boot method, but it was local to `Tu102`. Move it to
`Gsp::boot` so it applies to all boot methods.
This requires the HAL's `boot` method to return the `Result` for the
unload bundle's creation, so `Gsp::boot` can display the warning.

`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` 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.

The construction of the unload bundle is currently a bit convoluted and
could be done in one function instead of two.
Additionally, turn that function into a method of `Tu102`. A following
patch will turn the "use FWSEC bootloader" property into a flag of the
TU102 HAL itself, and making this a method will allow the code to access
it instead of querying `Chipset`.

By being in the TU102 HAL, we already know that the GSP boot method is
the SEC2 Booter, so the only variable is whether the FWSEC bootloader is
used or not. Since `Chipset` also includes the variants that boot FSP,
querying it for that information introduces a potential code path where
the chipset actually boots via FSP that the current code doesn't handle.
Turn the use of FWSEC bootloader into a property of the `Tu102` HAL, and
give Ampere chipsets their own instance with that property set to
`false`. This removes the invalid code path and the only use of
`Chipset` is now to load the correct firmware files.
This also removes some uses of the `Chipset::needs_fwsec_bootloader`
method and prepares the ground for removing it.

The GSP boot method is currently determined by two ad-hoc methods of
`Chipset`: `uses_fsp` (a boolean telling whether to use the FSP boot
path or the Sec2 Booter one) and `needs_fwsec_bootloader` (another
boolean valid only for the Sec2 Booter method that tells whether the
FWSEC bootloader must be used).
This is neither extensible nor sound: the combination `uses_fsp &&
needs_fwsec_bootloader` is invalid, but can still be expressed.
Thus, unify these two predicates into a single `gsp_boot_method` method
that returns an enum type unambiguously describing the boot method to
use. This ensures that no invalid combination can be expressed, which
makes matching sounder.

Add a local `Device` reference created from the `pci::Device` in the
`Gpu` constructor to avoid repeatedly calling `as_ref`.

We want to move the `Fsp` instance into `Gpu`, which will require
passing it as part of the `GspBootContext` as `Fsp::boot_fmc` is a
mutable method.
Additionally, we will also want to make some methods of the `Falcon`s
mutable, which will also require passing them as mutable references.
To prepare for this, make the passed `GspBootContext` mutable, and pass
mutable references to it to the GSP boot HAL methods.

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 also 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.
