ALSA: hda - Analog Devices AD1984A add HP Touchsmart model

Reference: ALSA bug #0004614
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4614

port-A (0x11)      - front hp-out
port-D (0x12)      - rear line out
port-E (0x1c)      - front mic-in
port-F (0x16)      - Internal speakers
digital-mic (0x17) - Internal mic

init verbs, mixers, jack sensing and PCI_QUIRK to support this hardware
