ALSA: hda - Merge all HDMI modules into the unified module

This patch merges all three patch_*hdmi variants to the single HDMI
parser.  There is only one snd-hda-codec-hdmi module now.

In this patch, the behavior of each parser isn't changed much.
The old ATI parser still doesn't use the dynamic parser yet.
In later patches, they'll be cleaned up.

Also, this patch gets rid of the individual snd-hda-eld module and
builds into snd-hda-codec-hdmi, since this is referred only from the
HDMI parser.
