dt-bindings: ehci/ohci: Allow iommus property

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

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.
