From: Ville Syrjälä <ville.syrjala at linux.intel.com>
intel_bw_calc_min_cdclk() is entirely pointless. All it manages to do is
somehow conflate the per-pipe min cdclk with dbuf min cdclk. There is no
(at least documented) dbuf min cdclk limit on pre-skl so let's just get
rid of all this confusion.
