feat(notifications): notifications pending interrupt
This patch injects a notification pending interrupt (NPI) into the
vCPU of a receiver with pending notification:
- If notification is global the NPI is injected at context switch from
NWd to the receiver SP, at the vCPU that the scheduler gave CPU cycles
to the receiver.
- If the notification is per-vCPU the notification is injected at the
handling of FFA_NOTIFICATION_SET, into the core that is specified in
arguments of the call. It should be handled when the SP and the
respective vCPU is next executed by the scheduler.
