firmware: arm_scmi: Port power protocol to new protocols interface
Convert internals of protocol implementation to use protocol handles and expose a new protocol operations interface for SCMI driver using the new get/put common operations, while keeping the old handle->power_ops still around to ease transition. Remove handle->power_priv now unused.
