DT and DT-conversion-related changes for various ARM platforms. Most
of these are to enable various devices on various boards, etc, and not
necessarily worth enumerating.
New boards and systems continue to come in as new devicetree files that
don't require corresponding C changes any more, which is indicating that
the system is starting to work fairly well.
A few things worth pointing out:
* ST Ericsson ux500 platforms have made the major push to move over to fully
support the platform with DT.
* Renesas platforms continue their conversion over from legacy platform devices
to DT-based for hardware description.
