Florian Zumbiehl 7041d9c3f0 USB: serial: pl2303: add support for tx xon/xoff flow control ...

Support hardware-level Xon/Xoff flow control in transmit direction with
pl2303.

I only know how to get the hardware to do IXON/!IXANY with ^S/^Q as control
characters, so I preserve the old behaviour for all other cases.
