s3c24xx_serial_console_txrdy() returned just 0 or 1 to indicate whether the TX is empty or not. Change its return type to bool.

Again, personally I think !! is just clutters the code here, as the function already returns bool. Other than that: Reviewed-by: Sam Protsenko <semen.protsenko@linaro.org>
