arm64: dts: ti: k3-am62x: Add overlay for IMX219

Browse Source 
RPi v2 Camera (IMX219) is an 8MP camera that can be used with SK-AM62A
through the 22-pin CSI-RX connector.

Same overlay can be used across SK-AM62* boards that have a 15/22-pin
FFC connector, so we name it with the k3-am62x- prefix.
