nova-core: Add support for VBIOS ucode extraction for boot
Add support for navigating and setting up 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.
Also add log messages to show the BIOS images.
