Fix the handling of certain devices.

Previously the foolowing lines would have broken:
controller      fdc0 at isa? disable port ? bio
controller      fdc0 at isa? disable port 0x100 bio

While this would work:
controller      fdc0 at isa? disable port "IO_FD1" bio

The first of the three lines is useful for making placeholder devices
for PCMCIA-floppies, and the second is useful for non-standard hardware.
The failure is a "(null)" string in ioconf.c that the compiler pukes on.
