commit dd5a089edfa51a74692604b4b427953d8e16bc35 upstream.

BugLink: https://launchpad.net/bugs/685161

The reporter of the bug states that he must use position_fix=1 to enable
capture for the internal microphone, so set it for his machine's PCI
SSID. Verified using 2.6.35 and the 2010-12-04 alsa-driver build.
