Since the driver was introduced the port features flags never extended.
As we don't expect more flags soon that would bypass the first
cacheline of ``struct s3c24xx_uart_info``, change the type of
``has_divslot`` to bool. Bitfields operations incur performance penalty
when set or read as compared to direct types.
