No, the problem that Alon has is that the firmware currently has no
way whatsoever to give a correct device tree, because of-serial.c
does not even know about ns16550a.

The patch adds both a special-case for the specific uart he
is using so that one is grandfathered in and a new compatible
value so future boards can specify both ns16550a and ns16550.
