Cezary Rojewski d24f1a090d ALSA: hda: Upgrade stream-format infrastructure
Introduce a set of functions that ultimately facilite SDxFMT-related
calculations in atomic manner:

First, introduce snd_pcm_subformat_width() and snd_pcm_hw_params_bits()
helpers that separate the base functionality from the HDAudio-specific
one.

snd_hdac_format_normalize() - format converter. S20_LE, S24_LE and their
unsigned and BE friends are invalid from HDAudio perspective but still
can be specified as function argument due to compatibility reasons.

snd_hdac_stream_format_bits() - obtain just the bits-per-sample value.
Does not ignore subformat and msbits parameters.

snd_hdac_stream_format() and snd_hdac_spdif_stream_format() - obtain the
SDxFMT value given the audio format parameters. The former is stripped
away of spdif-related information. Useful for users that do not care
about them.
