arm64: dts: qcom: sdm670: Affirm IDR0.CCTW on apps_smmu
On RPMh-based SoCs, the APPS SMMU advertizes support for cache-coherent
pagetable walk via the IDR0 register. This however is not respected by
the arm-smmu driver unless dma-coherent is set.
Mark the node as dma-coherent to ensure this (and other) implementations
take this coherency into account.
