ALSA: pcm: add IEC958 channel status helper Add a helper to create the IEC958 channel status from an ALSA snd_pcm_runtime structure, taking account of the sample rate and sample size.

ALSA: pcm: add IEC958 channel status helper for hw_params Add IEC958 channel status helper that gets the audio properties from snd_pcm_hw_params instead of snd_pcm_runtime. This is needed to produce the channel status bits already in audio stream configuration phase.
