		interrupt-map that contains PCIe related interrupts.

		that are defined in above interrupts property.
		For PCIe device node, it should define 6 mappings for
		the corresponding PCIe interrupts supporting the
		specification.

		1, 2 or 3.
		- qcom,pcie-active-config: boolean type; active configuration of PCIe
		addressing.
		- qcom,pcie-aggregated-irq: boolean type; interrupts are aggregated.
		- qcom,pcie-mhi-a7-irq: boolean type; MHI a7 has separate irq.
		- qcom,pcie-perst-enum: Link enumeration will be triggered by PERST
		deassertion.
		- mdm2apstatus-gpio: GPIO used by PCIe endpoint side to notify the host side.
		- Refer to "Documentation/devicetree/bindings/arm/msm/msm_bus.txt" for
		below optional properties:
		- qcom,msm-bus,name
