firmware: For no relocation skip two stage wait for secondary HARTs
When relocation is not required (i.e. _load_start == _link_start), we
can skip two stage wait for secondary HARTs. This means secondary HARTs
can skip the _wait_relocate_copy_done() loop and directly jump to the
_wait_for_boot_hart() loop when no relocation not required.
