[PATCH] dt-bindings: display: sun8i-mixer: Remove duplicated 'iommus'

[Fabio Estevam]

Commit 13871279ff5c ("arm64: dts: allwinner: h6: Fix Cedrus IOMMU usage")
introduced a double instance of 'iommus' causing the following build
error with 'make dt_binding_check':

found duplicate key "iommus" with value "{}" (original value: "{}")
  in "<unicode string>", line 45, column 3

Remove the double occurrence to fix this problem.

Fixes: 13871279ff5c ("arm64: dts: allwinner: h6: Fix Cedrus IOMMU usage")
