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

Browse Source 
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.
