pipeline: rpi: Add Recurrent and Needs32bitConv flags to RPi::Stream
Add a new "Recurrent" stream flag. This flag indicates the stream buffer
handling/management happend from the pipeline handler exclusively. This
is used for TDN/Stitch and Config streams.
Add a new Needs32bitConv stream flag to indicate that this stream needs
a software postprocessing conversion run on it before returning out to
the application.
