arm64: dts: ti: am62-phyboard-lyra: Add DT overlay for Lincoln LCD185-101CT panel
The panel is a Lincoln Technology Solutions LCD185-101CT [0]. It is a dual-link LVDS panel and supports WUXGA resolution (1920x1200). Furthermore, it has an I2C based touch controller: Goodix-GT928. Add an device tree overlay to support the Lincoln LCD185-101CT panel in combination with the phyBOARD-Lyra-AM62x.
