This commit adds a driver to conduct the AP's communication with the Runtime Security Subsystem (RSS). RSS is Arm's reference implementation for the CCA HES [1]. It can be considered as a secure enclave to which, for example, certain services can be offloaded such as initial attestation. RSS comms driver: - Relies on MHU v2.x communication IP, using a generic MHU API, - Exposes the psa_call(..) API to the upper layers.
