Remove Mini2440 and Lyre prototype 1 ports

Both targets were part of the (presumably dead) Lyre project
and no longer build. The Mini2440 was much more complete than
the Lyre and doesn't seem terribly difficult to fix up to the
point where it at least builds, if someone still cares -- but
given it is a dev board in a box, it's unlikely it ever saw
much use.
