From: Sumit Garg <redacted> Switch qcom media client drivers over to generic PAS TZ APIs. Generic PAS TZ service allows to support multiple TZ implementation backends like QTEE based SCM PAS service, OP-TEE based PAS service and any further future TZ backend service. Along with that pass proper PAS ID to set_remote_state API. As per testing the SCM backend just ignores it while OP-TEE makes use of it to for proper book keeping purpose.
