[PATCH] ppc32: Fix SCC Uart write problem after 2. open()

[Heiko Schocher]

Hello,

on a MPC8260 based Board, i succesfully wrote chars
over a SCC in UART Mode, but after i closed the port
and opened it again, the write() call failed! 
(cpm_uart_tx_empty()returns continually 0).
The following Patch will fix this problem.

thanks
Heiko Schocher
