ALSA: hda/realtek: Add alc256-samsung-headphone fixup

[ Upstream commit ef248d9bd616b04df8be25539a4dc5db4b6c56f4 ]

This fixes the near-silence of the headphone jack on the ALC256-based
Samsung Galaxy Book Flex Alpha (NP730QCJ). The magic verbs were found
through trial and error, using known ALC298 hacks as inspiration. The
fixup is auto-enabled only when the NP730QCJ is detected. It can be
manually enabled using model=alc256-samsung-headphone.
