[10/18] drm/i915: clean up and clarify audio related register defines

Message ID 0784ddc02d41e0c61060171a8b436f2c93d51fff.1412339886.git.jani.nikula@intel.com (mailing list archive)

Make audio related register defines conform to existing style: Add _MASK
where relevant, indent the defines for register contents, don't indent
the defines for register addresses, prefix pipe specific register
address defines with underscores, drop self explanatory comments.

No functional changes.
