dt-bindings: display: msm: qcm2290-mdss: Fix iommus property

Fix IOMMU DT propety for display 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 maximum value
for iommus property is updated accordingly.

These DT bindings changes should be backwards compatible.
