ALSA: hda - Drop unsol event handler for Intel HDMI codecs
We don't need to deal with the unsol events for Intel chips that are tied with the graphics via audio component notifier. Although the presence of the audio component is checked at the beginning of hdmi_unsol_event(), better to short cut by dropping unsol_event ops.
