Jiri Slaby 8ca01f8f70 tty: serial: switch mpc52xx_uart_int_{r,t}x_chars() to bool ...

mpc52xx_uart_int_rx_chars() returns unsigned int.
mpc52xx_uart_int_tx_chars() returns int.

The both results are binary ORed to the "keepgoing" variable. Unify all
three to bool as the only interesting value is whether we should keep
looping (true/false).
