[PATCH 01/10] ALSA: hda: Fix implicit PCM format type conversion

[Takashi Iwai <tiwai@suse.de>]

The PCM format type is defined with __bitwise, hence it can't be
passed as integer but needs an explicit cast.  In this patch, instead
of the messy cast flood, define the format argument of
snd_hdac_calc_stream_format() to be the proper snd_pcm_format_t type.

This fixes sparse warnings like:
  sound/hda/hdac_device.c:760:38: warning: incorrect type in argument 1 (different base types)
