[PATCH 2/3] arm64: dts: qcom: sm8150: add iommus to qups

[Caleb Connolly]

Hook up the SMMU for doing DMA over i2c. Some peripherals like
touchscreens easily exceed 32-bytes per transfer, causing errors and
lockups without this.

Fixes i2c on the OnePlus 7, without this touching the screen with more
than 4 fingers causes the device to lock up and reboot.
