Subject: ALSA: hda - Add MIC_NO_PRESENCE fixup for 2 HP machines

From: Hui Wang <hui.wang@canonical.com>

commit 322f74ede933b3e2cb78768b6a6fdbfbf478a0c1 upstream.

There is a headset jack on the front panel, when we plug a headset
into it, the headset mic can't trigger unsol events, and
read_pin_sense() can't detect its presence too. So add this fixup
to fix this issue.
