Perhaps all boards currently handled by this file do, but it's not true
for all mpc85xx_ds boards.  I think we could handle mpc8536ds here if we
didn't hardcode the uli assumption.  Not critical, but would be nice to
make this more device tree driven.

p1022ds OTOH is weird enough that it deserves its own board file.

You could export the primary detection function so that boards can call
it early if they want.
