For some architectures (e.g. openrisc, arc), BASE_BAUD isn't constant
And SERIAL_PORT_DFNS always use BASE_BAUND, and also all drivers use
SERIAL_PORT_DFNS to initialize static variables, statically.

So need define SERIAL_PORT_DFNS as empty to tell drivers they don't
support SERIAL_PORT_DFNS (mostly like frv and parisc did).

Oh, sorry, this patch is incorrect, need fix within the driver.

Thanks.
