Fixes to update.bin reloc (breaking!)

This fixes a regression in chainloading update.bin where the added check for if it's update or not, didn't copy the reloc code. And the calling was not updated to reflect this.

Additionally:
- Delete the reloc.S relic
- Force running config_hw in case we change hw init again in the future.
