[PATCH 10/10] arm64: dts: qcom: sm6375-pdx225: Configure Samsung touchscreen

Add a pretty bog-standard-for-Xperias-for-the-past-3-years
touchscreen setup.

The OEM that built the Xperia 10 IV for SONY decided to use some
kind of a GPIO regulator that needs to be enabled at all times
for both the touch panel and the display panel to function.
