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. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
