Hello build bot (Jenkins), Furquan Shaikh, Julius Werner, Rob Barnes, Karthik Ramasubramanian,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/56581

to look at the new patch set (#10).

Change subject: device/pci_rom: Add vga_oprom_preload
......................................................................

device/pci_rom: Add vga_oprom_preload

This method will allow preloading the VGA_BIOS_FILE. By preloading the
file, into cbfs_cache we reduce boot time. In the future we can also add
support for loading the second VGA_BIOS_FILE and the DGPU VGA_BIOS_FILE.

BUG=b:179699789
TEST=Boot guybrush to OS and verify 12 ms reduction in boot time
