gpu: nova-core: store Fsp instance in Gpu

Browse source

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 a GPU
sub-device, so its lifetime should match the GPU rather than a single
boot invocation.

It will also be 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.
