serial: imx: always wake up the processes in the TX callback
The current code only wakes up the processes when the circle
buffer has less data then the WAKEUP_CHARS.
But sometimes, the circle buffer may has data more then the WAKEUP_CHARS,
in such case, the processes will hang.
This patch makes it always wakes up the processes in the TX callback.
