arm64: dts: ti: am65x: Add Rocktech OLDI panel DT overlay

Browse Source 
The OLDI-LCD1EVM add on board has Rocktech RK101II01D-CT panel[1] with
integrated touch screen. The integrated touch screen is Goodix GT928.
This panel connects with AM65 GP-EVM[2].

Add DT nodes for these and connect the endpoint nodes with DSS.
