arm64: head: move dynamic shadow call stack patching into early C runtime
Once we update the early kernel mapping code to only map the kernel once
with the right permissions, we can no longer perform code patching via
this mapping.
So move this code to an earlier stage of the boot, right after applying
the relocations.
