The current dt binding for Exynos System MMU can be changed, if found
incompatible with the support for "Generic IOMMU Binding".
This patch adds a note to the binding documentation stating the same.

to implement child devices or sub-devices which are the client devices of the
System MMU.
+Note:
+The current DT binding for the Exynos System MMU is incomplete.
+The following properties can be removed or changed, if found incompatible with
+the "Generic IOMMU Binding" support for attaching devices to the IOMMU.

Required properties:
- compatible: Should be "samsung,exynos-sysmmu"
- reg: A tuple of base address and size of System MMU registers.
