arm64: dts: qcom: sc8280xp: Add PCIe IOMMU

Browse source

sc8280xp has an SMMUv3 connected to PCIe which is normally controlled by
QHEE and is thus transparent to the OS. However if we boot Linux in EL2,
without QHEE, we need to manage this IOMMU ourselves. To make that
easier, and since the hardware actually exists, just not "usually"
managed by Linux, describe it in the dts as "reserved".
