gpu: nova-core: Hopper/Blackwell: select FSP Chain of Trust version

The FSP Chain of Trust handshake is versioned: Hopper speaks version 1
and Blackwell speaks version 2. Provide the version through the FSP HAL
so the boot message carries the value FSP expects, and so chipsets that
do not use FSP need not express a version at all.
