Subject: [PATCH] ALSA: hda: intel-dsp-config: Fix Azulle Access 4 quirk detection

This device has an audio card which is quirked for force SOF use but the
device does not support SOF so the card is not usable and audio can't
play through the HDMI output.

Add another quirk detection that matches the Azulle Access 4 in the DMI
info.
