Subject: [PATCH 0/3] arm64: dts: qcom: Fix the msi-map entries

While adding the GIC ITS MSI support, it was found that the msi-map entries
needed to be swapped to receive MSIs from the endpoint.

But later it was identified that the swapping was needed due to a bug in
the Qualcomm PCIe controller driver. And since the bug is now fixed with
commit bf79e33cdd89 ("PCI: qcom: Enable BDF to SID translation properly"),
let's fix the msi-map entries also to reflect the actual mapping in the
hardware.
