gpu: nova-core: provide a clear error report for unsupported GPUs

Pass in a PCI device to Spec::new(), and provide a Display
implementation for boot42, in order to provide a clear, concise report
of what happened: the driver read NV_PMC_BOOT42, and found that the GPU
is not supported.

For very old GPUs (older than Fermi), the driver still returns ENODEV,
but it does so without a driver-specific dmesg report. That is exactly
appropriate, because if such a GPU is installed, it can only be
supported by Nouveau. And if so, the user is not helped by additional
error messages from Nova.

Here's the full dmesg output for a Blackwell (not yet supported) GPU:

NovaCore 0000:01:00.0: Probe Nova Core GPU driver.
NovaCore 0000:01:00.0: Unsupported chipset: boot42 = 0x1b2a1000 (architecture 0x1b, implementation 0x2)
NovaCore 0000:01:00.0: probe with driver NovaCore failed with error -524

gpu: nova-core: add boot42 support for next-gen GPUs

NVIDIA GPUs are moving away from using NV_PMC_BOOT_0 to contain
architecture and revision details, and will instead use NV_PMC_BOOT_42
in the future. NV_PMC_BOOT_0 will contain a specific set of values
that will mean "go read NV_PMC_BOOT_42 instead".

Change the selection logic in Nova so that it will claim Turing and
later GPUs. This will work for the foreseeable future, without any
further code changes here, because all NVIDIA GPUs are considered, from
the oldest supported on Linux (NV04), through the future GPUs.

Add some comment documentation to explain, chronologically, how boot0
and boot42 change with the GPU eras, and how that affects the selection
logic.

gpu: nova-core: gsp: Add GSP command queue bindings and handling

This commit introduces core infrastructure for handling GSP command and
message queues in the nova-core driver. The command queue system enables
bidirectional communication between the host driver and GSP firmware
through a remote message passing interface.

The interface is based on passing serialised data structures over a ring
buffer with separate transmit and receive queues. Commands are sent by
writing to the CPU transmit queue and waiting for completion via the
receive queue.

To ensure safety mutable or immutable (depending on whether it is a send
or receive operation) references are taken on the command queue when
allocating the message to write/read to. This ensures message memory
remains valid and the command queue can't be mutated whilst an operation
is in progress.

Currently this is only used by the probe() routine and therefore can
only used by a single thread of execution. Locking to enable safe access
from multiple threads will be introduced in a future series when that
becomes necessary.
