[PATCH v3] ALSA: hda/realtek: Add quirks for Unis H3C Desktop B760 & Q760

[dengxiang]

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.

---
V3:
- do some adjustment for eapd verbs and keep the capital letters for
  ALC_* enums.
v2:
- remove warning about unused variable 'spec'.

Looks almost good, but I forgot one more thing:

The table is sorted in SSID order, so please put at the right
