PCIe device in legacy mode can trigger interrupts using the wires #INTA, #INTB
,#INTC and #INTD. PCI devices are obligated to use #INTx for interrupts under
legacy mode. Each PCI slot or device is typically wired to different inputs on
the interrupt controller.
So, Define interrupt-map and interrupt-map-mask properties for device tree to
of map each PCI interrupt signal to the inputs of the interrupt controller.
