Abstract away the nuts and bolts of the SPI vs. PCI ROM
stuff, and hide it all in soc/intel_rom.c so that the
VBT code doesn't have to care about this stuff.
This leaves intel_bios.c with a single codepath that
can focus on the details related to the VBT layout.
This should have no functional changes.
v2: Rebase due to vbt_signature changes
Drop unnecessary cast (Jani)
