The Lenovo Yoga Pro 7 14IMH9 (DMI: 83E2) shares PCI SSID 17aa:3847
with the Legion 7 16ACHG6, but has a different codec subsystem ID
(17aa:38cf). The existing SND_PCI_QUIRK for 17aa:3847 applies
ALC287_FIXUP_LEGION_16ACHG6, which attempts to initialize an external
I2C amplifier (CLSA0100) that is not present on the Yoga Pro 7 14IMH9.

As a result, pin 0x17 (bass speakers) is connected to DAC 0x06 which
has no volume control, making hardware volume adjustment completely
non-functional. Audio is either silent or at maximum volume regardless
of the slider position.

Add a HDA_CODEC_QUIRK entry using the codec subsystem ID (17aa:38cf)
to correctly identify the Yoga Pro 7 14IMH9 and apply
ALC287_FIXUP_YOGA9_14IMH9_BASS_SPK_PIN, which redirects pin 0x17 to
DAC 0x02 and restores proper volume control. The existing Legion entry
is preserved unchanged.

This follows the same pattern used for 17aa:386e, where Legion Y9000X
and Yoga Pro 7 14ARP8 share a PCI SSID but are distinguished via
HDA_CODEC_QUIRK.
