Have sio return BIS_PROBE_DEFAULT like all the other drivers in the

Browse Source 
tree...  John Baldwin noted that sio might pass values between probe
and attach via softc.  It appears that sio does leave the hardware in
a known state after probing, so other drivers that try to probe might
leave it in a worse state.  It doesn't seem to pass any data in softc,
however, that I could find...  I think we should not be probing for
anything but nonPnP isa, but that's a change for another day.
