Depending on whether the device is forced to use a specific discipline, the device_type then specifies further attributes. Shift the common attributes into dev->groups, so that the device_type only contains the discipline-specific attributes. This avoids exposing the common attributes to the disciplines, and nicely cleans up our sysfs code. While replacing the qeth_l*_*_device_attributes() helpers, switch from sysfs_*_groups() to the more generic device_*_groups().
