Revert "drm/i915: Ignore panel type from OpRegion on SKL"



This reverts commit bb10d4ec.

Since commit c8ebfad7 ("drm/i915: Ignore OpRegion panel type except
on select machines") we ignore the OpRegion panel type except for
specific machines (handled via a DMI match), so having SKL explicitly
excluded from using the OpRegion panel type is redundant. So let's
remove the SKL check.
