Both PCI core and IDE interpret a zero length resource as unassigned.
That is probably better than clearing the flags in retrospect.

setup-pci is for SFF8038i devices. It therefore knows that for assigned
resources they must be I/O. It also assumes that zero is not a valid I/O
port just like zero is not a valid IRQ. Stick a real IDE resource at zero
and drivers/ide can't cope.
