From: Manivannan Sadhasivam <manivannan.sadhasivam@xxxxxxxxxx>
Qcom PCIe RC controllers are capable of generating 'global' SPI interrupt
to the host CPUs. This interrupt can be used by the device driver to
identify events such as PCIe link specific events, safety events, etc...
Hence, add it to the PCIe RC node along with the existing MSI interrupts.
