A OHCI/EHCI controller could be behind an IOMMU, in which case an iommus
property assigns the stream ID for this device.
Allow that property in the DT bindings to fix a complaint about the Arm Juno
board's DTS file.

I need acks for this and the first dt-binding in order to take it
via ARM SoC. Also where ever possible split arm64 and arm DT in case
ARM SoC wants different PR. I will ask if you have to respin.
