Add get_eld audio component for i915/HD-audio

Here are the patchset to add get_eld op to audio component for communicating more directly between i915 and HD-audio.

Currently, the HDMI/DP audio status and ELD are notified and obtained via the hardware-level communication over HD-audio unsolicited event and verbs although the graphics driver holds the exactly same information. As we already have a notification via audio component, this is another step forward; namely, the audio driver may fetch directly the audio status and ELD via the new component op.

The commits are based on Dave's latest drm-next branch.

Daniel, would you pull this one, or should we postpone it for 4.6? The changes aren't too intrusive, so I prefer having it for 4.5, so that we can continue developing the MST audio stuff based on this.

thanks,

Takashi
