[ALSA] Support 3-bytes 24bit format in PCM OSS emulation
Add the support of 3-bytes 24bit formats in PCM OSS emulation. Also removed snd_pcm_build_linear_format() function. It's exported just for OSS emulation, and now the code was changed without calling this function. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
