Subject: [PATCH 4/5] dt-bindings: remoteproc: qcom,sm8550-pas: Document Glymur ADSP

Document compatible for Qualcomm Glymur SoC ADSP which is fully compatible
with SM8750 ADSP. Also with the Linux Host running on EL2, the remoteprocs
need to be hypervisor independent, the iommu property is mandatory to
ensure proper functionality.

Signed-off-by: Sibi Sankar <sibi.sankar@....qualcomm.com>
