[PATCH 1/5] device-port: Add a latency variable to the port struct

[poljarinho@xxxxxxxxx (poljar (Damir Jelic))]

From: poljar <poljarinho@xxxxxxxxx>

A latency offset variable was added to the port struct and a function to
set the latency offset.

The latency offset does nothing for now, but it will be later added to
the sink/source latency.
