I really don't like having always-included code take over the absolute
start of the zImage's address space.  The whole idea in my entry
cleanup patch is that the platform code gets control of the "head.S"
area, so we can potentially support platforms with conflicting
hard-wired requirements for things at specific offsets.

I think this belongs in a ps3.o, which will define _zimage_start to be
identical to the reset vector.
