pcm: add and describe SND_PCM_FORMAT_{S, U}20

Browse source 
This patch adds and describes in various functions that query format
properties SND_PCM_FORMAT_{S,U}20 formats that were recently added to the
kernel as SNDRV_PCM_FORMAT_{S,U}20.

These formats are similar to existing 20-bit PCM formats
SND_PCM_FORMAT_{S,U}20_3, however they occupy 4 bytes instead of 3.
