hvmloader: Move option ROM loading into a separate optionnal file
Make load_rom field in struct bios_config an optionnal callback rather
than a boolean value. It allow BIOS specific code to implement it's
own option ROM loading methods.
Facilities to scan PCI devices, extract an deploy ROMs are moved into
a separate file that can be compiled optionnaly.
