alsa: don't assume that hw:x is an analog output

Browse source 
Previously, if front:x didn't work, we would try to use hw:x for analog
stereo output. There's no guarantee that hw:x is an analog output,
however. For example, the Intel HDMI LPE driver uses hw:x for HDMI
output, and PulseAudio incorrectly created analog profiles for that
card, because front:x doesn't work but hw:x does.

This patch changes things so that the analog stereo mapping doesn't any
more use hw:x as a fallback. A separate "unknown stereo" fallback
mapping is added to handle the rare case where hw:x is the only PCM
device that works.
