arm64: dts: ti: k3-j721e-sk: Model CSI2RX connector mux
J721E SK has the CSI2RX routed to a MIPI CSI connector and to 15-pin
RPi camera connector through an analog mux with GPIO control, model that
so that an overlay can control the mux state according to connected
cameras. Also provide labels to the I2C mux bus instances so that a
generic overlay can be used across multiple platforms.
