ALSA: hda - bug fix for invalid connection list of Haswell HDMI codec pins
Haswell HDMI codec pins may report invalid connection list entries, which will cause failure to play audio via HDMI or Display Port. So this patch adds fixup for Haswell to workaround this hardware issue: enable DP1.2 mode and override the pins' connection list entries with proper value.
