Uwe Kleine-König 7d07ada047 serial: mpc52xx: let tx_empty callback return either 0 or TIOCSER_TEMT 
Documenation/serial/driver requests that the tx_empty callback should
return 0 if there are still chars in the fifo or shifter or TIOCSER_TEMT
(0x01) if no character is pending to be sent.

Fix the mpc52xx serial driver to not return MPC52xx_PSC_SR_TXEMP (i.e.
0x0800) but TIOCSER_TEMT as documented.
