Subject: [PATCH v1] ALSA: hda/tas2781: Enable init_profile_id for device initialization
Optimize the time consumption of profile switching, init_profile saves
the common settings of different profiles, such as the dsp coefficients,
etc, which can greatly reduce the profile switching time comsumption and
remove the repetitive settings.
