DRM Rust changes for v7.2-rc1

- Driver Core (shared via signed tag dd-lifetimes-7.2-rc1):

- Introduce Higher-Ranked Lifetime Types (HRT) for Rust device
drivers, allowing driver structs to hold device resources like
pci::Bar and IoMem directly with a lifetime tied to the binding
scope, removing the need for Devres indirection and ARef<Device>.

- Replace drvdata() with scoped registration data on the auxiliary
bus, using the new ForLt trait to thread lifetimes through
registrations. Remove drvdata() and driver_type.

- DRM:

- Add GPUVM immediate mode abstraction for Rust GPU drivers:
- In immediate mode, GPU virtual address space state is updated
during job execution (in the DMA fence signalling critical path),
keeping the GPUVM and the GPU's address space always in sync.

- Provide GpuVm, GpuVa, and GpuVmBo types for managing address
spaces, virtual mappings, and GEM object backing respectively.

- Provide split-merge map/unmap operations that handle partial
overlaps with existing mappings.

- drm_exec integration for dma_resv locking and GEM object
validation based on the external/evicted object lists are not
yet covered and planned as follow-up work.

- Introduce DeviceContext type state for drm::Device, allowing
drivers to restrict operations to contexts where the device is
guaranteed to be registered (or not yet registered) with userspace.

- Add FEAT_RENDER flag to the Driver trait for render node support.

- Nova:

- Hopper/Blackwell enablement:
- Add GPU identification and architecture-based HAL selection for
Hopper (GH100) and Blackwell (GB100, GB202).

- Implement the FSP (Foundation Security Processor) boot path used by
Hopper and Blackwell, including FSP falcon engine support, EMEM
operations, MCTP/NVDM message infrastructure, and FSP Chain of
Trust boot with GSP lockdown release.

- Add support for 32-bit firmware images and auto-detection of
firmware image format.

- Add architecture-specific framebuffer, sysmem flush, PCI config
mirror, DMA mask, and WPR/non-WPR heap sizing.

- GSP boot and unload:
- Refactor the GSP boot process into a chipset-specific HAL,
keeping the SEC2 and FSP boot paths separated cleanly.

- Implement proper driver unload: send UNLOADING_GUEST_DRIVER
command, run Booter Unloader and FWSEC-SB upon unbinding, and run
the unload bundle on Gsp::boot() failure. This removes the need
for a manual GPU reset between driver unbind and re-probe.

- GA100 support:
- Add support for the GA100 GPU, including IFR header detection and
skipping, correct fwsignature selection, conditional FRTS boot,
and documentation of the IFR header layout.

- VBIOS hardening and refactoring:
- Harden VBIOS parsing with checked arithmetic, bounds-checked
accesses, and FromBytes-based structure reads throughout the FWSEC
and Falcon data paths. Simplify the overall VBIOS module
structure.

- HRT adoption:
- Use lifetime-parameterized pci::Bar directly, replacing the
Arc<Devres<Bar0>> indirection. Replace ARef<Device> with &'bound
Device in SysmemFlush and the GSP sequencer. Separate the driver
type from driver data.

- Misc:
- Rename module names to kebab-case (nova-drm, nova-core).

- Require little-endian in Kconfig, making the existing assumption
explicit.

- Tyr:

- Define comprehensive typed register blocks for GPU_CONTROL,
JOB_CONTROL, MMU_CONTROL (including per-address-space registers),
and DOORBELL_BLOCK using the kernel register!() macro. This replaces
manual bit manipulation with typed register and field accessors.

- Add shmem-backed GEM objects and set DMA mask based on GPU physical
address width.

- Adopt HRT: separate driver type from driver data, and use IoMem
directly instead of Devres for register access during probe.

- Move clock cleanup into a Drop implementation.

gpu: nova-core: move lifetime to `Bar0`

gpu: nova-core: move lifetime to `Bar0`

Currently Nova code uses `&'a Bar0` a lot. This is `&'a Mmio`, where `Mmio`
represents an owned MMIO region; this type only exists as a target for
`Deref` so `Bar` and `IoMem` can share code and should be avoided to be
named directly. The upcoming I/O projection series would make `Io` trait
much simpler to implement, and thus the owned MMIO type would be removed
in favour of direct `Io` implementation on `Bar` and `IoMem`.

Add lifetime parameter to `Bar0<'a>` and change it to be alias of `&'a
pci::Bar<'a, ..>`. This also prepares Nova core so that when I/O projection
series land, this could be changed to using a MMIO view type directly which
avoids double indirection.

gpu: nova-core: Hopper/Blackwell: larger non-WPR heap

Hopper and Blackwell need a larger non-WPR heap than the 1 MiB that
earlier architectures use. Hopper and Blackwell GB10x need 2 MiB, while
Blackwell GB20x needs 2 MiB + 128 KiB. These sizes diverge by family,
so give Hopper and each Blackwell family its own framebuffer HAL and
select the non-WPR heap size per chipset family.
