[Intel-gfx] [PATCH 9/9] drm/i915: Extract bdw_get_buf_trans_edp()

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Make the BDW and SKL code a bit more similar by extracting the
low vswing handling for BDW into a helper, as we already have
it like that for SKL+.
