[PATCH] ALSA: hda/realtek: Add quirk for HP Elite Dragonfly Max G2 speaker

[Ruairi Anthony]

The HP Elite Dragonfly Max G2 Notebook PC (SSID 103c:8890) uses an
ALC285 codec but is missing from the existing HP quirk table, unlike
the related "HP Elite Dragonfly G2" entry (SSID 103c:8716). Without
the quirk the right speaker amplifier's GPIO is never initialized,
leaving it silent while the left speaker plays normally.

Apply the existing ALC285_FIXUP_HP_GPIO_AMP_INIT fixup used by the
103c:8716 entry, which resolves the issue. Verified with speaker-test
on both channels and confirmed correct routing to both the downward-
firing woofer and upward-firing tweeter on each side via the board's
passive crossover.

Applied now.  Thanks.
