feat(notifications): bind and unbind
Handle bind and unbind interfaces. The bind interface is intended for a
given receiver to enable a sender to set the specified notifications.
The unbind interface revokes the sender's ability to set the specified
notifications.
Bindings are tracked per notification in the receiver's vm structure.
This patch adds handling to FFA_NOTIFICATION_BIND and
FFA_NOTIFICATION_UNBIND, functions to validate the bindings,
as well as to make any bindings updates.
