DisplayColorCalibration: Increase range

Along with associated kernel patch, increases the range of the display
tuner. Adjusts the "/sys/class/misc/gammacontrol/tuner" node to contain
an RGB triplet from 0 to 120, with "60 60 60" being nominal values

Individual gamma corrections can be also be found by tweaking the nodes
in /sys/class/misc/gammacontrol
