Ok, my impression on this was that of_serial is the right solution
in general, but it often gets initialized too late to debug some
of the interesting parts of the boot sequence.

Unless we take handling of soc serial ports completely out of
legacy_serial, I think it should handle ebony just like the other
boards.

Because of the way the serial layer works, it does exactly the
right thing if you have both drivers enabled, i.e. it starts
out using the first port when legacy_serial detects it, but later
of_serial finds it as well, and wires up all the logic to connect
both the serial ports to the right device tree nodes.
