-    PCI: imx6: ventana: fixup for IRQ mismapping
-    
-    The TI XIO2001 PCIe-to-PCI bridge used on several Ventana expansion boards
-    has its slot-to-bridge IRQ mapping reversed from the PCI specification:
-    
-      INTA->INTD
-      INTB->INTC
-      INTC->INTB
-      INTD->INTA
-    
-    Implement a custom swizzle function that does a fixup on the interrupt for
-    devices on a TI XIO2001 bridge.
-
