The TI XIO2001 PCIe-to-PCI bridge used on Ventana expansion boards

  INTD->INTA

Implement a custom swizzle function that does a fixup on the interrupt for
devices on the first TI XIO2001 bridge in the tree.

I'm pretty sure you can express that by using a more specific
'interrupt-map' property that defines the correct mapping for
the PCIe-to-PCI bridge in the board file.
