[ Upstream commit f2dbe87c5ac1f88e6007ba1f1374f4bd8a197fb6 ]
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.
