Lyude Paul 9ac7d53d70 drm/i915: Auto detect DPCD backlight support by default ... Turns out we actually already have some companies, such as Lenovo, shipping machines with AMOLED screens that don't allow controlling the backlight through the usual PWM interface and only allow controlling it through the standard EDP DPCD interface. One example of one of these laptops is the X1 Extreme 2nd Generation. Since we've got systems that need this turned on by default now to have backlight controls working out of the box, let's start auto-detecting it for systems by default based on what the VBT tells us. We do this by changing the default value for the enable_dpcd_backlight module param from 0 to -1.
