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.

are the calls to set_remote_state required?
0 is not the IRIS/VENUS remote processor.

If it is legacy, maybe they can be phased out?
FWIW, in msm-3.10 (yes) QCOM_SCM_SVC_BOOT/0x0a used to be called
'TZBSP_VIDEO_SET_STATE', taking the arguments:

args[0] = suspend->0, resume->1
args[1] = spare=0

seems like sdm845/msm-4.9 still had that and so did 8250/msm-4.19
