Some changes for option roms: 

- don't make users pick the name. Names for option roms are in the v3-defined
format of pci%04x,%04x.rom with the vendor and device id filling in the 
%04x. 
- users pass in vendor and device id. 
- users pass in a dest. If the dest is 0, the address of the ROM image in 
FLASH is returned. If the address is non-zero, then the decmpressor is called,
and it will make sure the ROM image is copied to the destination (even 
in the uncompressed case).

move qemu over to always using ROMFS
