Relocate the code that technically fits in the pin initializer into the
initializer itself.
While, thanks to pin_init_scope(), it is also possible to keep it as is,
moving appropriate code into the initializer has the advantage that it
structures the dependencies of fields naturally.
For instance, intermediate data that is only needed for a single field
goes into the initializer block of this field, making it obvious that it
is not needed by anything else.
On the other hand, intermediate data that is needed for multiple fields
to initialize remains above the initializer, naturally indicating that
it is needed my multiple fields.

The GSP requires some pieces of metadata to boot. These are passed in a
struct which the GSP transfers via DMA. Create this struct and get a
handle to it for future use when booting the GSP.

Compute more of the required FB layout information to boot the GSP
firmware.
This information is dependent on the firmware itself, so first we need
to import and abstract the required firmware bindings in the `nvfw`
module.
Then, a new FB HAL method is introduced in `fb::hal` that uses these
bindings and hardware information to compute the correct layout
information.
This information is then used in `fb` and the result made visible in
`FbLayout`.
These 3 things are grouped into the same patch to avoid lots of unused
warnings that would be tedious to work around. As they happen in
different files, they should not be too difficult to track separately.

Use the newly-introduced `num` module to replace the use of `as`
wherever it is safe to do. This ensures that a given conversion cannot
lose data if its source or destination type ever changes.

As per [1], we need one "use" item per line, in order to reduce merge
conflicts. Furthermore, we need a trailing ", //" in order to tell
rustfmt(1) to leave it alone.
This does that for the entire nova-core driver.

The GSP bootloader is a small RISC-V firmware that is loaded by Booter
onto the GSP core and is in charge of loading, validating, and starting
the actual GSP firmware.
It is a regular binary firmware file containing a specific header.
Create a type holding the DMA-mapped firmware as well as useful
information extracted from the header, and hook it into our firmware
structure for later use.
The GSP bootloader is stored into the `GspFirmware` structure, since it
is part of the GSP firmware package. This makes the `Firmware` structure
empty, so remove it.

The GSP firmware is a binary blob that is verified, loaded, and run by
the GSP bootloader. Its presentation is a bit peculiar as the GSP
bootloader expects to be given a DMA address to a 3-levels page table
mapping the GSP firmware at address 0 of its own address space.
Prepare such a structure containing the DMA-mapped firmware as well as
the DMA-mapped page tables, and a way to obtain the DMA handle of the
level 0 page table.
Then, move the GSP firmware instance from the `Firmware` struct to the
`start_gsp` method since it doesn't need to be kept after the GSP is
booted.
As we are performing the required ELF section parsing and radix3 page
table building, remove these items from the TODO file.
