feat(notifications): get notifications from SPs
Handling the call FFA_NOTIFICATION_GET to retrieve pending notifications
from SPs:
- SPMC retrieves the pending notifications from the partition's bitmap
field;
- Hypervisor forwards the call to SPMC, analyzes the returned value
and populates its return to the VM.
Hypervisor case useful to test notifications full signaling flow from
NWd.
