ALSA: hda/realtek: Headset fixup for Clevo NH77HJQ

On Clevo NH77HJ, NH77HP, and their 15" variants, there is a headset microphone input attached to 0x19 that does not have a jack detect. In order to get it working, the pin configuration needs to be set correctly, and a new ALC256_FIXUP_SYSTEM76_MIC_NO_PRESENCE fixup is applied. This is similar to the existing System76 quirk for ALC293, but for ALC256.
