ALSA: hda/realtek: Add quirk for Lenovo Xiaoxin 14 GT

The Lenovo Xiaoxin 14 GT (Chinese market model, AMD Ryzen AI 9 365)
produces constant electrical hissing and crackling noise from both
internal speakers and 3.5mm headphone jack during audio playback.
Audio works correctly on Windows. The noise is louder than the audio
itself and is present on all tested distributions (Arch Linux, Fedora 44,
kernels 6.12 and 7.0-zen).

The PCI SSID 17aa:3912 is not present in the quirk list. Additionally,
in some configurations the BIOS reports the SSID as 17aa:0000, causing
the kernel to apply no fixup at all:

  snd_hda_codec_alc269 hdaudioC1D0: ALC287: picked fixup for PCI SSID
17aa:0000

Codec info (/proc/asound/card1/codec#0):
  Codec: Realtek ALC287
  Vendor Id: 0x10ec0287
  Subsystem Id: 0x17aa3912
  Revision Id: 0x100002

Audio devices:
  c2:00.1 AMD/ATI Radeon HD Audio [1002:1640]
  c2:00.5 AMD Audio Coprocessor [1022:15e2]
  c2:00.6 AMD Ryzen HD Audio Controller [1022:15e3]

GPIO state (all zeros, amplifier appears uninitialized):
  IO[0-4]: enable=0, dir=0, data=0

The proposed fixup ALC287_FIXUP_YOGA9_14IAP7_BASS_SPK_PIN is chosen
by analogy with neighboring Lenovo 14" AMD models (17aa:3911, 17aa:390d)
that use the same fixup. However, this has NOT been verified by testing
a compiled kernel — I do not currently have a working Linux installation
on this machine. Guidance from maintainers on the correct fixup is
very welcome.
