Keep loading custom roms (e.g. from -option-rom) with rom_add_file starting at 0xc8000.
Modify SeaBIOS to scan the memory range for pre-deployed option roms before deploying
PCI roms. SeaBIOS will find the last pre-deployed rom and have a starting address for
deploying PCI roms. This will keep ISA option roms working.
