Revert "drm/i915: Add option to support dynamic backlight via DPCD"
This reverts commit ae25eceab616d16a07bcaa434b84463d58a3bdc3.
The DPCD backlight commits regress a Thinkpad X1 Carbon 4th Gen and a
BXT-P (in CI). Enabling dynamic backlight boots to a black screen, and
enabling DPCD backlight leads to a black screen after suspend/resume.
