[PATCH] ppc32: Re-add embed_config.c to ml300/ep405

[PATCH] ppc32: Re-add embed_config.c to ml300/ep405

Commit bdf7d963d97455253f342c3a246a6146c02d1e3d (ppc32: cleanup AMCC PPC40x
eval boards to support U-Boot) broke the kernel for ML300 / EP405.

It still compiles as there's a weak definition of the function in
misc-embedded.c, but the kernel crashes as the bd_t fixup isn't performed.
