dt-bindings: PCI: qcom-ep: Describe optional IOMMU
Some of Qualcomm platforms have an IOMMU unit between the PCIe IP and
DDR. For example, the SA8775P specifies the iommu alththough it is not
a part of bindings.
Thus, change the schema in order to require the IOMMU for SA8775P and
forbid it from being used on SDX55 (SM8450 will be handled in a later
patch).
This fixes the following warning:
pcie-ep@1c10000: Unevaluated properties are not allowed ('iommus' was unexpected)
Fixes: 9d3d5e75f31c ("dt-bindings: PCI: qcom-ep: Add support for SA8775P SoC")
