Input: wacom - add Intuos5 Touch Ring LED support
The Touch Ring LEDs on Intuos5 tablets use a different report format which supports only 4 levels of brightness. We remap the 7-bit value obtained from sysfs to an appropriate value for the tablet. Control of the crop mark LEDs (new to the I5) is left for a later patch.
