spa: add Latency param and object

Browse source 
Add a new latency param that contains a latency object.
The latency object contains the min and max delay from a port to
the terminal sink/source. It is also possible to express this
delay as a fraction of the quantum to avoid having to recalculate
the latency every time the quantum changes.
