[linux-oem][PATCH 2/2] ALSA: hda - fix headset mic problem for Dell machines with alc236

[Hui Wang]

BugLink: http://bugs.launchpad.net/bugs/1729500

We have several Dell laptops which use the codec alc236, the headset
mic can't work on these machines. Following the commit 736f20a70, we
add the pin cfg table to make the headset mic work.
