ALSA: HDA: Fix internal mic on Dell E5420/E5520
This is a fixup for the 2.6.38 kernel, as the issue is being resolved
by upstream commits 699d899560cd7e72da39231e584412e7ac8114a4 and
094a42452abd5564429045e210281c6d22e67fca - which are too invasive
to reach 2.6.38. Instead make pin fixes as a workaround.
