Allow Cyrix 5530 based UltraDMA IDE controllers to co-exist with other
devices on the PCI bus.
This is a workaround for a bug in the Cx5530 PCI bus logic that will
hog the PCI bus if the disk is fast enough. UDMA mode 2 is fast enough
to make this happen so limit the drives to mode 1. The symptom is
missed interrupts and sio  silo overflows at high async speeds.
