[PATCH v3 1/3] dt-bindings: display: samsung,exynos7-decon: add properties for iommus and ports

[Kaustabh Chakraborty]

Similar to FIMD and Exynos5433's DECON, the Exynos7 DECON hardware:
- May optionally require an IOMMU to initialize a display region.
- May require a port connection to another block, say an MIC or a DSI
  master.

Document these bindings in the devicetree schema.
