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.
Fixes: 4c65d7054b4c ("arm64: dts: exynos: gs101: Add ufs and ufs-phy dt nodes")
