ALSA: hda/realtek: Add quirks for Unis H3C Desktop B760 & Q760

These models use NSIWAY amplifiers for internal speaker, but cannot put
sound outside from these amplifiers. So eapd verbs are needed to initialize
the amplifiers. They can be added during boot to get working sound out
of internal speaker.
