feat(indirect message): add FFA_MSG_SEND2 support
FF-A v1.1 indirect message FFA_MSG_SEND2 support, allowing indirect
messaging between any endpoint (VM and SP).
When one of the endpoints is an SP, the SPMC is responsible for message
delivery to the receiver, potentially in the other world.
In order to allow cross world communication the SPMC is aware of VM
mailboxes and the Hypervisor forwards the FFA_MSG_SEND2 message to the
SPMC when the receiver is an SP.
