As per testing the SCM backend just ignores it while OP-TEE makes
use of it to for proper book keeping purpose.

This should not be in the middle of a mildly related series..
The PAS IDs should be centralized into a single header. And the
name of the driver shouldn't be part of the define. I would guesstimate
that on the secure side it's probably called VPU or VIDEO

I agree with your comments, this is something I would also like to
consolidate on OP-TEE side as well: see discussion here [1].

However, the patch itself was needed to do book keeping on OP-TEE side
but I can drop it since anyhow the video isn't functional yet in
upstream dependent on the proper IOMMU support.
