2017-05-03nb/intel/gm45: Set display backlight according to EDID stringArthur Heymans
Add some known good values for some thinkpads displays. Known good means that at this pwm frequency the display is evenly lit on all duty cycles, the display makes minimal to no noise at lower duty cycles and the display does not flicker. This values differs from vendor (which uses an obviously wrong display clock (190MHz instead of 320MHz) resulting in frequency more than 60% off the intended value. TESTED on Thinkpad X200 with edid ascii string in list and removed from list to see if notice message is shown.
