media: dt: bindings: media: Document practices for DT bindings, ports, endpoints

Browse Source 
Port and endpoint numbering has been omitted in DT binding documentation
for a large number of devices. Also common properties the device uses have
been missed in binding documentation. Make it explicit that these things
need to be documented.

Documenting bindings for devices
--------------------------------
All required and optional bindings the device supports shall be explicitly
documented in device DT binding documentation. This also includes port and
endpoint nodes for the device, including unit-addresses and reg properties where
relevant.
