ALSA: hda - Disable tigger at pin-sensing on AD codecs
Analog Device codecs seem to have problems with the triggering of pin-sensing although their pincaps give the trigger requirements. Some reported that constant CPU load on HP laptops with AD codecs. For avoiding this regression, add a flag to codec struct to notify explicitly that the codec doesn't suppot the trigger at pin-sensing.
