<title>gpu: nova-core: move lifetime to `Bar0`</title>

<id>urn:sha1:99676aed1fec109d62822e21a06760eb098dc5f4</id>
<content type='text'>
Currently Nova code uses `&amp;'a Bar0` a lot. This is `&amp;'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&lt;'a&gt;` and change it to be alias of `&amp;'a
pci::Bar&lt;'a, ..&gt;`. 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.

For non-sec2 it is only required to wait for GSP falcon to halt. This is
because GSP does the main work of unloading on GPUs not using sec2.

After FSP Chain of Trust completes, the driver must poll for lockdown

bit and helper functions needed for this polling.

Hopper and Blackwell use FSP instead of SEC2 for secure boot. The
driver must wait for FSP secure boot to complete before continuing
with GSP bring-up. Poll for boot success with a 5-second timeout, and
return the FSP interface only on success so that later Chain of Trust
operations cannot run before FSP is ready. The interface owns the FSP
falcon and the FMC firmware.

FSP is the Falcon that runs FMC firmware on Hopper and Blackwell.
Load the FMC ELF in two forms: the image section that FSP boots from,
and the full Firmware object for later signature extraction during
Chain of Trust verification. Declare the FMC image in the module's
firmware table so it is bundled for FSP-based chipsets.
