drm/i915: simplify intel_ddi_pll_select()

Browse Source 
Because {hsw,skl,bxt}_ddi_pll_select all pretty much do the same thing
in slightly different ways. Replace everything with a simple copy of
the function and inline it inside intle_ddi_pll_select().

v2: s/return pll/return pll != NULL/ (Ville)
