arm64: dts: ti: k3-j721e-sk: Add overlay for IMX219

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.
