With the availability of generic PAS service, let's add SCM calls as a backend to keep supporting legacy QTEE interfaces. The exported qcom_scm* wrappers will get dropped once all the client drivers get migrated as part of future patches.

Ack.
Coming back to this comment again, since this is a temporary wrapper which is going to be dropped as part of 2nd last patch, I don't think there is value to fix them as they maintain existing APIs interface.
