9061c997fc audio/pcm_decode.c: skip extra chunk of wav header 
Summary:
- The wav header parser in /dev/audio/pcm device driver expects the 'data'
  chunk is placed just after the 'fmt ' chunk.
- Because the wav files generated by FFmpeg places 'LIST' chunk which
  contains the music track information between 'fmt ' and 'data' chunks,
  nxplayer cannot playback the files.
- This patch skips extra chunks after 'fmt ' chunk to find the 'data' chunk.

Impact:
- All architectures which support /dev/audio/pcm device.

Testing:
- Tested by Raspberry Pi Pico audio driver.
- nxplayer can playback the wav files which are created by FFmpeg after
  applying this patch.
