Subject: [PATCH RFT 00/12] firmware: arm_ffa: Add FF-A v1.1 notifications support

The series adds initial support for the notifications added in FF-A v1.1
The notification mechanism enables a requester/sender endpoint to notify
a service provider/receiver endpoint about an event with non-blocking
semantics.

A notification is akin to the doorbell between two endpoints in a
communication protocol that is based upon the doorbell/mailbox mechanism.

The framework is responsible for the delivery of the notification from the
sender to the receiver without blocking the sender. The receiver endpoint
relies on the OS scheduler for allocation of CPU cycles to handle a
notification.

OS is referred as the receiver’s scheduler in the context of notifications.
The framework is responsible for informing the receiver’s scheduler that
the receiver must be run since it has a pending notification.
