[PATCH] ALSA: hda/realtek: Enable 4-speaker output Dell Precision 5560 laptop

[acheronfail]

This is my first patch, so let me know if I need to do anything
differently. :)

The Dell Precision 5570 uses the same 4-speakers-on-ALC289 just like the
previous Precision 5560. I replicated that patch onto this one, and can
confirm that the audio is much better (the woofers are now working);
I've tested it on my Dell Precision 5570.
