[PATCH v2 12/15] net: ipa: Switch to generic PAS TZ APIs

[Sumit Garg]

From: Sumit Garg <sumit.garg@xxxxxxxxxxxxxxxx>

Switch ipa client driver 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.
