Some changes required to get yabel working on v2 (and they generally make

sense, too). Have one u64 instead of three.

In order to use the old bios emulator, you have to do nothing. (Default, if
CONFIG_PCI_ROM_RUN is enabled)

In order to use yabel in your target, you need to add the following lines to
your config:
  uses CONFIG_PCI_OPTION_ROM_RUN_YABEL
  default CONFIG_PCI_OPTION_ROM_RUN_YABEL=1

In order to use vm86 in your target, you need to add the following lines to
your config:
  uses CONFIG_PCI_OPTION_ROM_RUN_VM86
  default CONFIG_PCI_OPTION_ROM_RUN_VM86=1
Note: vm86 only works on platforms with _RAMBASE in the lower megabyte.
