qemu is about to change the way how option roms are loaded. pci roms
will be loaded into a option rom bar (like real hardware does).
non-pci roms can be loaded using the qemu firmware interface.
With this change seabios will deploy all roms instead of having qemu
copy them to the 0xc0000 -> 0e0000 range. Advantages are:
* roms can be packed better, especially in case they resize themself
(like the gPXE roms do).
* rom area is a bit larger as seabios can additionally use the
unused regions of the 0xe0000 segment.
* the whole process comes closer to what happens on real hardware.
