pandaboard.xml: fix ALSA mix config for audio input

This adjusts the ALSA configuration to match a working config Perry
put together for audio input.

To test a kernel driver, use these on a Linux host:

$ adb shell tinycap /data/local/tmp/test.wav -D0 -c 1 -d 1 -r 48000 -p 1 -n 2 -b 16
  [... pause, then ^C]
$ adb pull /data/local/tmp/test.wav /tmp/test.wav
$ aplay -r 48000 -c 1 -f s16_LE -t raw /tmp/test.wav
