[Intel-gfx] [PATCH 2/3] drm/dp/i915: Clean up clock configuration for HDMI audio

[Dhinakaran Pandiyan]

No functional change, just clean up. Debug messages now print out clock
units. Additionally, the configuration bits, which are 1:1 mapped to the
clock frequency and don't convey much information are not printed out.
