Devices: Unify Port Gathering method

All devices that support it use the same mechanism to gather ports
so this patch removes the individual implementations in favor
of a single one in IDevice.cpp.

This patch also removes:
* canAutodetectPorts() as it was not used.
* Port::parseFrom...Output as they are not used anymore.
