ipa: ipu3: Cache line duration at configure call

Browse source 
We use the line duration several times in the IPAIPU3. Instead of
recalculating it each time, cache the value as a utils::Duration.
ExposureTime and FrameDuration units are in micro-seconds, cast the
Duration accordingly.

As sensorInfo is no longer used in updateSessionConfiguration remove the
reference to it.
