HID: roccat: allow readout of koneplus sensor register data
tcu sysfs attr was used to only control calibration process so far. Direct sensor register access possibility has been revealed. Allowing readout of tcu permits usage of this feature. Signed-off-by: Stefan Achatz <erazor_de@users.sourceforge.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
