ALSA: hda: Fix position reporting on Poulsbo
Hans reported that his Sony VAIO VPX11S1E showed the broken sound
behavior at the start of the stream for a couple of seconds, and it
turned out that the position_fix=1 option fixes the issue. It implies
that the position reporting is inaccurate, and very likely hitting on
all Poulsbo devices.
The patch applies the workaround for Poulsbo generically to switch to
LPIB mode instead of the default position buffer.
