Note that unless your driver supports the "full" resume,
SNDRV_PCM_INFO_RESUME shouldn't be set. Here, the "full" resume means
that the hardware gets back to a completely sane state and the PCM
streams are resumed without extra PCM prepare call at PM resume.
If the PCM (or whatever) needs another re-initialization (like in many
cases), don't set this flag.
Just to be sure...
