Aleksander Morgado 5d176a1e61 base-modem: explicitly say if NET or TTY data ports are supported 
A modem that creates exclusively bearer objects that work with NET
ports (e.g. all QMI or MBIM modems) must not add any TTY port in the
list of data ports.

A modem that creates exclusively bearer objects that work with TTY
ports (e.g. the generic modem) must not add any NET port in the
list of data ports.

A modem that may use both TTY and NET ports should add all in the list
of data ports.
