gpu: nova-core: vbios: Add support for FWSEC ucode extraction

Browse source

Using the support for navigating the VBIOS, add support to extract vBIOS
ucode data required for GSP to boot. The main data extracted from the
vBIOS is the FWSEC-FRTS firmware which runs on the GSP processor. This
firmware runs in high secure mode, and sets up the WPR2 (Write protected
region) before the Booter runs on the SEC2 processor.

Tested on my Ampere GA102 and boot is successful.
