[PATCH 2/2] arm64: dts: qcom: sm8450: Allow both GIC-ITS and internal MSI controller

[Manivannan Sadhasivam]

The devicetree should specify both MSI implementations and the OS/driver
should choose the one based on the platform requirements. Currently, Linux
DWC driver will choose GIC-ITS over the internal MSI controller.

Fixes: a11bbf6adef4 ("arm64: dts: qcom: sm8450: Use GIC-ITS for PCIe0 and PCIe1")
