Update AudioPort <-> configs mapping

It is considered that in general there is a 1:N relationship
between an AudioPort and AudioPortConfigs.
The 'AudioPort.activeConfig' field could only support a 1:1
relationship, thus it got removed. Instead,
an 'AudioPortConfig.portId' field added to reference the ID
of the AudioPort to which this config is linked to.
