From: Ville Syrjälä ville.syrjala@linux.intel.com
Split the LPE audio platform data into a port specific chunk and device specific chunk. Eventually we'll have a port specific chunk for each port, 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.
v2: Organize per port instead of per pipe
