[PATCH] ALSA: hda/realtek: Add quirk for Lenovo Yoga Pro 7 14IRH8

[Moritz Baron]

The Lenovo Yoga Pro 7 14IRH8 (ALC287 codec, subsystem ID 0x17aa:0x38b1)
has bass speakers on pin 0x17 that are not routed through a DAC with
volume control. This causes the bass speakers to play at full volume
regardless of the volume slider position.

Apply ALC287_FIXUP_YOGA9_14IAP7_BASS_SPK_PIN which corrects the DAC
routing for pin 0x17, enabling proper volume control. This is the same
fix used for other Yoga Pro 7 models with identical audio topology
(14APH8, 14AHP9, 14ASP10, 14IAH10).

Your machine seems to have a different PCI SSID (17aa:3852) from the
entry above, so it's not appropriate to put here.

Instead, put one before the entry of 17aa:3852 below, with a brief
comment that it's for avoiding the confliction with the PCI SSID
17aa:3852.

... the conflicting entry is found here above.

v2: Move the quirk entry before 17aa:3852 and add a comment to
    clarify the PCI SSID conflict, as suggested by Takashi Iwai.

Applied to for-next branch now.  Thanks.
