arm64: dts: qcom: sar2130p: 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
ccb2fd725d ("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.

Fixes: be9115bfe5 ("arm64: dts: qcom: sar2130p: add support for SAR2130P")
