device: provide option to always load PCI option roms
Certain kernel drivers require the presence of option rom
contents because the board's static configuration information
is located within the blob. Therefore, allow a chipset/board to
instruct the pci device handling code to always load but not
necessarily run the option rom.
BUG=chrome-os-partner:25885
BRANCH=baytrail
TEST=Both enabling and not enabling this option shows expected behavior.
