[PATCH v8 4/9] dt-bindings: qcom-qce: Add 'iommus' to optional properties

[Vladimir Zapolskiy <vladimir.zapolskiy@linaro.org>]

From: Bhupesh Sharma <bhupesh.sharma@linaro.org>

Add the missing optional property - 'iommus' to the
device-tree binding documentation for qcom-qce crypto IP.

This property describes the phandle(s) to apps_smmu node with sid mask.
