* Split out s3c24xx_serial_tx_chars from s3c24xx_serial_tx_irq,
where only the latter acquires the port lock. This will be necessary
on platforms which have edge-triggered IRQs, as we need to call
s3c24xx_serial_tx_chars to kick off transmission from outside IRQ
context, with the port lock held.
* Rename s3c24xx_serial_rx_chars to s3c24xx_serial_rx_irq for
consistency with the above. All it does now is call two other
functions anyway.
