Can you change this to use

	if (IS_ENABLED(CONFIG_SERIAL_8250_FSL)) && ...

The resulting code will be the same, it just get a little easier
on the eye.

Other than that, I wonder if we should do this completely differently
and have the respective entries in of_platform_serial_table[] with
an appropriate PORT_* constant to handle the freescale case.
