This patch adds support for hart hotplug in OpenSBI using a generic WFI based approach. Hart hotplug can be achieved via SBI HSM extension which allows supervisor mode software to start or stop any harts anytime. Any platform wishes to implement platform specific hart hotplug must implement both hart_start and hart_stop in addition to enable platform feature SBI_PLATFORM_HAS_HART_HOTPLUG.
