ALSA: hda/realtek: Add quirk for Intel NUC 10

This adds a new SND_PCI_QUIRK(...) and applies it to the Intel NUC 10
devices. This fixes the issue of the devices not having audio input and
output on the headset jack because the kernel does not recognize when
something is plugged in.

The new quirk was inspired by the quirk for the Intel NUC 8 devices, but
it turned out that the NUC 10 uses another pin. This information was
acquired by black box testing likely pins.

Hi,
this is my second ever submitted kernel patch with the first one send just some minutes ago, feel free to criticise me if I made an error or missed a best practice bullet point.
Also: I'm unsure if this would fit the requirements for stable@...r.kernel.org and/or trivial@...nel.org, but I think not (correct me if I'm wrong).
Kind regards
Werner Sembach
