More fixes for ppc serial drivers seem to be needed since next-0701 (exclusive):

drivers/serial/mpc52xx_uart.c: In function 'mpc52xx_uart_int_rx_chars':
drivers/serial/mpc52xx_uart.c:735: error: 'struct uart_info' has no member named 'tty'
drivers/serial/mpc52xx_uart.c: In function 'mpc52xx_uart_of_probe':
drivers/serial/mpc52xx_uart.c:1277: warning: cast to pointer from integer of different size


drivers/serial/uartlite.c: In function 'ulite_receive':
drivers/serial/uartlite.c:78: error: 'struct uart_info' has no member named 'tty'
drivers/serial/uartlite.c: In function 'ulite_isr':
drivers/serial/uartlite.c:165: error: 'struct uart_info' has no member named 'tty'

The following patch just fixes the build errors gcc emitted; if more
is needed to make the drivers actually work, it's wasn't blatently

The patch is against next-0703, but I don't think it will matter.
