Subject: [PATCH] PENDING: arm64: dts: qcom: sm8550: switch iris iommus to
 iommu-map

Add a dt-bindings header include/dt-bindings/media/qcom,sm8550-iris.h
defining IRIS_NON_PIXEL_VCODEC (0) and IRIS_PIXEL (1) function IDs.

Switch the iris video codec node in sm8550 (kailua) from the legacy
'iommus' property to 'iommu-map', using the above function IDs to
identify the non-pixel and pixel context bank SMMU stream mappings.
