RPi v2 Camera (IMX219) is an 8MP camera that can be used with SK-AM69, J721E SK, and AM68 SK through the 22-pin CSI-RX connector. Add a reference overlay for dual IMX219 RPI camera v2 modules which can be used across AM68 SK, AM69 SK, TDA4VM SK boards that have a 15/22-pin FFC connector. Also enable build testing and symbols for all the three platforms.
