[Intel-gfx] [PATCH 12/13] drm/i915: Fold ibx_pch_dpll_prepare() into ibx_pch_dpll_enable()

[Ville Syrjala]

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

Move the FP divider programming into ibx_pch_dpll_enable(). No reason
that I can see why these would have to be programmed this early.
