[PATCH v2] ALSA: hda: Add HP MP9 G4 Retail System AMS to force connect list

["Steven 'Steve' Kendall" <skend@xxxxxxxxxxxx>]

In recent HP UEFI firmware (likely v2.15 and above, tested on 2.27),
these pins are incorrectly set for HDMI/DP audio. Tested on
HP MP9 G4 Retail System AMS. Tested audio with two monitors connected
via DisplayPort.

Changes in v2:
- Now instead adds value to force connect list as suggested in review.
- I tested these changes with two monitors via DP, results identical to v1.
