arm64: dts: ti: k3-am67a-beagley-ai: Add overlay for IMX219 on CSI1

Browse Source 
RPi v2 Camera (IMX219) is an 8MP camera that can be used with BeagleY AI
through the 22-pin CSI-RX connectors. Add a DT overlay to enable use of
this camera sensor through the CSI1 connector.

The CSI1 connector is muxed with DSI0, so ensure that we route it to
CSI1 (DSI_CSI_OE=0 and DSI_CSI_SEL=1).
