arm64: dts: ti: Add LincolnTech OLDI LCD-185 Overlay for AM625-BeaglePlay

Browse Source 
The panel is 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 DT overlay for the OLDI panel to connect with BeaglePlay platform.
