igb ufm support
It'd be nice to enable support for ufm information in igb and allowing us to read the igb eeprom. This change works with 12759 and makes igb the first consumer of the new interfaces. Being able to read the eeprom is also useful for figuring out if folks have hardware the support some of the weirder sensor interfaces as well as general introspection. This will add the ability to both report and read UFM images.
