arm64: dts: exynos8895-dreamlte: enable support for the touchscreen

Browse Source 
The Samsung Galaxy S8 uses a Samsung s6sy761 touchscreen over hsi2c23.
Add a node for it in order to allow using the touchscreen as long as
the previous bootloader has enabled the required regulators because
there's no support for PMIC yet.
