Subject: move build/boot/rom moverom to handle/make/config

most of these steps do not need to be repeated, per image.

move it into handle/make/config, so that the steps are
performed on files that go under elf/coreboot (this will
save on build time).

the logic for handling 4MB ROM images on sandy/ivy was unused,
and has been removed.
