Switch the iris video codec node in sa8775p (lemans) from the legacy 'iommus' property to 'iommu-map', using IRIS_NON_PIXEL_VCODEC and IRIS_PIXEL function IDs to identify the non-pixel and pixel context bank SMMU stream mappings respectively.

@qcomlnxci qcomlnxci requested a review from a team April 9, 2026 09:54
As per memory map, video firmware memory region is 7MB for sa8775*
variants while it is 16MB for qcs9100* variants. Keeping the 7MB variant
of video firmware in ride common DTS does not allow qcs9100* to pick the
16MB variant. Drop it from common and define in respective variant DTS.
