Re: [PATCH 1/2] arm64: dts: exynos: gs101: ufs: add dma-coherent property

ufs-exynos driver configures the sysreg shareability as cacheable for gs101 so we need to set the dma-coherent property so the descriptors are also allocated cacheable.

This fixes the UFS stability issues we have seen with the upstream UFS driver on gs101.
