[PATCH] ALSA: hda/realtek: Fix speakers on Alienware x16 R2

[Oliver Ohrt]

The Alienware x16 R2 has two pairs of speakers, but the BIOS
marks pin 0x17 as unused, so only the pin 0x14 pair plays and
audio is very quiet/dull.

Apply ALC289_FIXUP_DUAL_SPK like on other Dell machines to set
up pin 0x17 and route it to DAC1. Tested on my x16 R2 with
kernel 6.18.38, and now all speakers play at full volume.
