serial: omap: Fix "unused" warnings with SERIAL_PRESENT=n and OF_REAL=y

The definition of our ID table (and of_to_plat function) is guarded with
OF_REAL however the U_BOOT_DRIVER that would in turn use the table is
guarded with SERIAL_PRESENT. To avoid a potential warning we must also
guard both with SERIAL_PRESENT.
