arm64: dts: mt8365-evk: Add goodix touchscreen support
The Mediatek Genio 350-EVK board has on the DSI0 connector a StarTek
KD070FHFID015 display panel that uses a Goodix GT9271 I2C capacitive
touch controller.
The mt8365-evk devicetree already have the display panel support but
lacks the touchscreen support, so add it.
