These are DSP working modes, such as noise suppression, echo cancellation...
The reason we won't have a specific name on alsa control is that the driver
will be more flexible and we can define customized modes on the firmware.
For example, the 5 modes may be noise suppression 1, noise suppression 2,
noise suppression + echo cancellation, voice tracking, echo cancellation.
