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.
v2: Use HAS_GMCH_DISPLAY() to more cleanly describe the platforms that
actually want to use GMCH-style panel fitting. (Ville)
