Ville Syrjälä aeddda06c1 drm/i915: Ignore panel type from OpRegion on SKL 
Dell XPS 13 9350 apparently doesn't like it when we use the panel type
from OpRegion. The OpRegion panel type (0) tells us to use use low
vswing for eDP, whereas the VBT panel type (2) tells us to use normal
vswing. The problem is that low vswing results in some display flickers.
Since no one seems to know how this stuff is supposed to be handled,
let's just ignore the OpRegion panel type on SKL for now.

v2: Print the panel type correctly in the debug output
