Routine Description:
Given an EFI image filename, create a ROM-able image by creating an option

option ROM header + PCI data structure + EFI image out to the output file.
Arguments:
Argc - standard C main() argument count
Argv - standard C main() argument list
Returns:
0 success
non-zero otherwise
