ALSA: hda - Enable sync_write for AMD chipset with IDT 92HD8x codecs 



The AMD chipset seems unstable in the normal operation mode, and it
seems requring more sensible access for each verb.  Enabling sync_write
mode and allowing bus-reset is a sort of workaround for these chipset
stability issues.
