arm64: dts: ti: k3-am69-sk: Enable camera peripherals

CSI cameras are controlled using I2C. On AM69 Starter Kit, this is routed
to I2C-1, so enable the instance, TCA9543 I2C switch and the TCA6408
GPIO expander on the bus. AM69 SK has the CSI2RX routed to a MIPI CSI
connector and to 22-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.
