Clean up the edd.c driver.

* use kobject_set_name() instead of snprintf() per GregKH's recommendation.
* Add MODULE_VERSION()
* s/driverfs/sysfs/ in Kconfig
* Remove report URL message, as there have been too many BIOSs reported,
  virtually none of which are EDD-capable.  This may return if/when I
  develop a better reporting method and database to capture/store the
  data from users.
* Remove the unused code for creating a symlink to the scsi_device.
  This never worked right, and I'm going to show the relationship from
  a userspace tool which uses libsysfs instead.
