armv8: move reset branch into boot hook
The boot0 hook we have so far is applied _after_ the initial branch to the "reset" entry point. An upcoming change requires even this branch to be changed, so we apply the hook macro at the earliest point, and have the branch in the hook file as well. This is no functional change at this point, just refactoring to simplify upcoming patches.
