[RFC PATCH v9 1/7] dt-bindings: PCI: Add definition of PCIe WAKE# irq and PCI irq

[Jeffy Chen <jeffy.chen@rock-chips.com>]

We are going to handle PCIe WAKE# pin for PCI bus bridges and PCI
devices in the pci core, so add definitions of the optional PCIe
WAKE# pin for PCI bus bridges and PCI devices.

Also add an definition of the optional PCI interrupt pin for PCI
devices to distinguish it from the PCIe WAKE# pin.
