drm/i915: Convert the ddi cdclk code to get_display_clock_speed

Unify the HSW/BDW/SKL cdclk extraction code to conform to the same
.get_display_clock_speed() mold that all the other platforms
use.

v2: Update due to SKL code getting added

v3: Rebase on top of -nightly (introduction of intel_audio.c) (Mika Kahola)
