PCM: Add string conversion helper functions for chmap
Added a few helper functions between chmap and string.
snd_pcm_chmap_type_name() -- a string of the given chmap type
snd_pcm_chmap_name() -- a string of the given channel position
snd_pcm_chmap_print() -- print channel map on the given buffer
snd_pcm_chmap_from_string() -- get a channel position from string
snd_pcm_parse_string() -- parse the whole channel map from string
