[Intel-gfx] [PATCH 08/11] drm/i915: Make i9xx_crtc_clock_get() work for PCH DPLLs

[ville.syrjala at linux.intel.com]

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

Just add the 120MHz reference clock case, and magically the
function appears to be ready to for PCH DPLLs.

Now, 120MHz might not always be correct, but we're already using
hardocoded values for other platforms, so the situation isn't
getting much worse.
