BXT CRTC scaling uses the same gen9 codepaths as SKL; these codepaths store panel fitter information in pipe_config->pch_pfit. However since HAS_PCH_SPLIT() is false for BXT we never actually wind up filling in this structure (we wind up filling in pipe_config->gmch_pfit instead, which is ignored when we go to program the hardware). Make sure we always take the PCH code path on gen9+ platforms.
