H A Dserial_pl01x.c96baa4c37695b4dac2bde981f59c38e7af19f2eb Sun Oct 02 11:52:52 UTC 2011 Linus Walleij <linus.walleij@linaro.org> serial: pl01x: drain PL01x FIFO before baudrate change

Not draining the FIFO and waiting for the UART to be non-busy
before changing baudrate results in crap characters on the
console, so let's wait for the FIFO to drain and the last
character to be clocked out before we do that.
