Subject[20/20] USB: cp210x: do not map baud rates to B0
2.6.32-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Johan Hovold <jhovold@gmail.com>

commit be125d9c8d59560e7cc2d6e2b65c8fd233498ab7 upstream.

We do not implement B0 hangup yet so map low baudrates to 300bps.
