With the quirk handling in patch 3, I think we should remove the public interface
and EXPORT_SYMBOL(), as well as move this header file into mach-mvebu.

That said, we may want to add support for the soc_bus later on (not as part of the
stable bug fix) to make it possible to query the soc version from user space through
the standard sysfs files.
