[ALSA] hdspm - Fix autosync bug 

* better report of speed mode change failures
* autosync_ref control bugfix (was reporting pref_sync_ref instead)
  (changed HDSPM_AES32_AUTOSYNC_FROM_NONE value to comply with array
  indexing in snd_hdspm_info_autosync_ref())
* added support for master modes up to 192kHz (clock source control
  value was restricted up to 96kHz)
