software/ors-amarisoft: ru/lopcomm: Simplify and clarify cu_config.jinja2.xml 

We can use mathematical relation in between ports, channels and tx/rx endpoints
to bring structure and clarity in RU setup.

Also, while on it, document how tx/rx data flow are organized as it was not
clear just from reading ORAN specs and I had to deduce it.
