bsps: Add CLOCK_DRIVER_USE_ONLY_BOOT_PROCESSOR
Add CLOCK_DRIVER_USE_ONLY_BOOT_PROCESSOR clock driver option. If
defined, then do the clock tick processing on the boot processor on
behalf of all other processors. Currently, this is intended as a
workaround for a Qemu shortcoming on ARM.
Update #2737.
