[PATCH] ALSA: hda/realtek: Add quirk for HP ENVY 13-aq1xxx

[Tarun Noonemunthala <ntarun2000@gmail.com>]

The HP ENVY Laptop 13-aq1xxx (PCI SSID 103c:86ad) uses an ALC285 codec
with two speaker pairs: front (pin 0x14) and bottom (pin 0x17).

The BIOS leaves pin 0x14 as [N/A] ("not connected"), so the generic
parser never enables the front pair and only the bottom speakers are
audible.  The vendor driver (RTKVHD64.sys) programs that pin with the
value 0x90170150 and runs the HP amplifier initialization, which is
already implemented in the driver as ALC285_FIXUP_HP_GPIO_AMP_INIT.

Add a board fixup that applies the pin configuration for 0x14 and chains
to the existing amplifier init fixup.

The pin value was recovered from the vendor driver's own configuration
data.  The patch and this changelog were prepared with an AI coding
assistant (see the Assisted-by tag below); the change was reviewed and
tested by the submitter on the affected machine.

Tested on an HP ENVY 13-aq1xxx by rebuilding snd-hda-codec-alc269 from
the Fedora 7.1.10 source and loading it: the codec now reports
"line_outs=2 (0x14/0x17)", pin 0x14 comes up as an output (Pin-ctls
0x40) with its amplifier unmuted, and both speaker pairs play.
