drm/i915: Simplify scanline_offset handling for gen2
Currently intel_crtc_scanline_offset() is careful to always
return a positive offset. That is not actually necessary
as long as we take care of negative values when applying the
offset in __intel_get_crtc_scanline().
This simplifies intel_crtc_scanline_offset(), and makes
the scanline_offfset arithmetic more symmetric between
the forward (__intel_get_crtc_scanline()) and reverse
(intel_crtc_scanline_to_hw()) directions.
