Something has changed in the hardware on LNL/BMG because
HDMI outputs no longer have the extra scanline offset.

I confirmed that MTL still has the old behaviour, which
is a bit weird since both MTL and BMG have display ver 14
vs. LNL is version 20. But can't argue with actual
hardware behaviour.

  drm/i915: Fix scanline_offset for LNL+ and BMG+
  drm/i915: Reverse the scanline_offset if ladder
  drm/i915: Replace the HAS_DDI() in intel_crtc_scanline_offset() with
    specific platform checks
