drm/amd/display: fix calculation for the pwl backlight curve
[Why]
The PWL backlight curve is used by the firmware to convert between
brightness and linear PWM value.
Driver has a backlight LUT, but the firmware holds a PWL curve and
interpolates between points.
The calculations are incorrect leading to slightly off backlight values
being programmed.
[How]
Fix the PWL backlight curve threshold/offset calculations
