[romprefix] Sanity-check the runtime segment address for PCI 3
Some PCI 3 BIOSes seem to provide a garbage value in %bx, which should
contain the runtime segment address. Perform a basic sanity check: we
reject the segment if it is below the start of option ROM space. If
the sanity check fails, we assume that the BIOS was not expecting us
to be a PCI 3 ROM, and we just leave our image in situ.
