gpu: nova-core: Hopper/Blackwell: skip GFW boot waiting

Browse source

Hopper and Blackwell GPUs use FSP-based secure boot and do not
require waiting for GFW_BOOT completion. Add a Gh100 GPU HAL that
returns Ok(()) for wait_gfw_boot_completion(), and route Hopper
and Blackwell architectures to it.
