Atish Patra	5b4824082f	lib: Add possible hart status values ... SBI HSM extension defines possible hart status values in the specification. Define all possible status values. Add a helper function to convert hart state to status because hart states are internal to OpenSBI only and may not match the status values defined in the specification.

Atish Patra	b677a9b8d6	lib: Implement hart hotplug ... 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.
