arm64: dts: qcom: agatti: Fix IOMMU DT properties

Fix IOMMU DT propeties for GPU, display and video peripherals via
dropping SMMU stream IDs which relates to secure context bank.

This problem only surfaced when the Gunyah based firmware stack is
ported on Agatti replacing the legacy QHEE based firmware stack. Assigning
Linux kernel (HLOS) VMID to secure context bank stream IDs is treated
as a fault by Gunyah hypervisor which were previously ignored by QHEE
hypervisor.

The DT changes should be backwards compatible with legacy QHEE based
firmware stack too.
