The commit 6b31a9744b87 ("arm64: dts: qcom: sdm845: Affirm IDR0.CCTW on apps_smmu") enabled dma-coherent property for the IOMMU device. This works for some devices, like Qualcomm RB3 platform, but at the same time it breaks booting on Lenovo Yoga C630 (most likely because of some TZ differences). Disable DMA coherency for IOMMU on Lenove Yoga C630.

Let's revert the offending commit instead, this must have been some sort of fw development fluke..
