[PATCH] serial: ns16550: Fix an "unused" warning with SERIAL_PRESENT=n and OF_REAL=y

[Tom Rini <trini@konsulko.com>]

The definition of our ID table 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 the
ID table with SERIAL_PRESENT.
