soc/intel/skylake: Map VBIOS IDs
The extracted VBIOS Option ROM ships the same ID for several
generations, not matching the ID on the hardware resulting in a
mismatch, and coreboot does not run the Option ROM.
PCI ROM image, vendor ID 8086, device ID 0406,
ID mismatch: vendor ID 8086, device ID 5916
Add the appropriate mappings.
TEST=coreboot runs the ROM on the TUXEDO Book BU1406.
