[Intel-gfx] [PATCH v2] drm/i915/display: nuke skl workaround for pre-production hw

[Lucas De Marchi]

According to intel_detect_preproduction_hw(), the SKL stepping D0 is
still pre-preproduction so we can nuke the additional workaround.
WA database says it applies to all steppings, but bspec disagrees.
After talking to HW people they said it was fixed either on B0 or D0.

While at it, nuke dangling new line.

v2: fix typo in commit message (Michael) and note that W/A db disagrees
    with the steppings this is applicable (Ville).
