[PATCH v2 2/3] media: dt-bindings: venus: Fix iommus property

[Sumit Garg <sumit.garg@kernel.org>]

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

Fix IOMMU DT propety for venus via dropping SMMU stream IDs which
relates to secure context bank. Assigning Linux kernel (HLOS) VMID
to secure context bank stream IDs is incorrect.

The min value is added for iommus property to ensure in future when
secure context bank stream IDs are properly supported then the iommus
property is extensible.

These DT bindings changes should be backwards compatible.
