[PATCH] ALSA: hda/realtek: Add quirk for Lenovo Yoga 7 2-in-1 14AKP10

[Rocket Raccoon]

The Lenovo Yoga 7 2-in-1 14AKP10 (PCI subsystem ID 0x17aa:0x391c) uses
an ALC287 HDA codec paired with a TAS2781 amplifier connected via I2C.
Without this quirk the amplifier is not initialised and internal speaker
output lacks amplification.

The Signed-off-by line must be a real name or a known identity as it's
a legal requirement.  (Also it's better aligned with From line.)

... and the patch seems not applicable cleanly.  Please fix your
mailer setup, too.
