ARM: dts: imx7d-pico-pi: add OV5645 camera support

Browse Source 
Add OV5645 camera device node and enable relevant components in the
video capture data path, so output stream can be captured, and the
camera itself can be controlled over I2C bus.

This is roughly based on descriptions found in downstream kernel tree [1],
adapted to match upstream bindings.
