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



[ Upstream commit 73f1c75d5e6bd8ce2a887ef493a66ad1b16ed704 ]

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.
