arm64: dts: qcom: qcs6490-radxa-dragon-q6a: Fix the PCIe iommu-map entries
The IOMMU provider apps_smmu uses '#iommu-cells = <2>', but the PCIe
iommu-map entries specify only one cell for the SID, omitting the SID
mask. This went unnoticed until the OF core started warning with commit
ccb2fd725d41 ("of: Respect #{iommu,msi}-cells in maps"):
iommu-map has 1-cell entries targeting 2-cell #iommu-cells, treating as 1-cell output
So fix the entries to match the provider's '#iommu-cells' property.
