ti-st: use worker instead of calling st_int_write in wake up

Browse Source 
The wake up method is called with the port lock held. The st_int_write
method calls port->ops->write with tries to acquire the lock again,
causing CPU to wait infinitely. Right way to do is to write data to port
in worker thread.
