RPi v2 Camera (IMX219) is an 8MP camera that can be used with SK-AM69
through the 22-pin CSI-RX connector.
Same overlay can be used across AM68 SK, TDA4VM SK boards that have a
15/22-pin FFC connector. Also enable build testing and symbols for
all the three platforms.

You need to also add this "k3-am69-sk-csi2-imx219.dtb" to the list:
dtb- +=
below for it to actually get build tested.
