[PATCH] ALSA: hda/realtek: Add quirk for HP Pavilion x360

[Takashi Iwai]

HP Pavilion x360 sets a bogus PCI SSID (103c:0000), hence the driver
picks up a wrong quirk entry, resulting in an almost silent output.
And yet, the existing quirk for x390 doesn't seem sufficing, and we
need the extra setup for the amp.

This patch adds the quirk entry for the codec SSID (103c:8486) to
initialize the amp via COEF verbs and chains to the existing quirk for
another x360 model to address the silent output.
