From: Sumit Garg <sumit.garg@oss.qualcomm.com>

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.
