ALSA: hda/realtek: Enable 4-speaker output Dell Precision 5570 laptop

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.

Glad to hear. One more thing I forgot to mention, though:
if you keep the name in From field different from Signed-off-by line, you can embed the From tag into the patch itself, too, so that it's applied consistently.

That is, a patch text will be:

I already applied this patch with the correction in my side now, so it's just a hint for the next submission :)

thanks,
