arm64: secmon: direct non-BSP cpus to start before BSP
The arch_run_on_all_cpus[_async]() APIs can run the BSP before
the APs if the BSP's id is less than the APs' ids. Fix this by
ensuring we run the necessary callback on all but self.
BUG=chrome-os-partner:33532
BRANCH=None
TEST=Booted spin table kernel. All CPUs are up.
