ALSA: hda/tas2781: select program 0, conf 0 by default

Browse Source 
commit ec1de5c214eb5a892fdb7c450748249d5e2840f5 upstream.

Currently, cur_prog/cur_conf remains at the default value (-1), while
program 0 has been loaded into the amplifiers.

In the playback hook, tasdevice_tuning_switch tries to restore the
cur_prog/cur_conf. In the runtime_resume/system_resume,
tasdevice_prmg_load tries to load the cur_prog as well.

Set cur_prog and cur_conf to 0 if available in the firmware.
