[Intel-gfx] [PATCH 08/11] drm/i915: Clean up the LPE audio platform data

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Split the LPE audio platform data into a pipe specific
chunk and device specific chunk. Eventually we'll have
a pipe specific chunk for each pipe, but for now we'll
stick to just one.

We'll also get rid of the intel_hdmi_lpe_audio_eld structure
which doesn't seem to have any real reason to exist.
