HID: roccat: correction and cleanup of HID feature reports
Removed analog feature report enums and modified code in roccat_common to reflect this. Non standard conform Kone got its own copy of the old code. That helps extracting more generalizations for newer devices. Signed-off-by: Stefan Achatz <erazor_de@users.sourceforge.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
