[PATCH 7/8] ax88796: Add X-Surf 100 zorro driver providing an ax88796 platform device
Add platform device driver to populate the ax88796 platform data from
information provided by the XSurf100 zorro device driver.
This driver will have to be loaded before loading the ax88796 module,
or compiled as built-in.
