documentation/iommu: update description of ARM System MMU binding
This patch adds descriptions for new properties of the device tree
binding for the ARM SMMU architecture. These properties control
arm-smmu driver options.

[will: removed device isolation property, as this has been dropped and
fixed up spacing in documentation]
