audio:hal: Fix to set ASRC mode for use case with combo device

 -Asrc mode is not getting set on headphone device for ringtone
  playback with concurrent native DSD or 44.1 Khz playback.
  Check and set ASRC mode is done in select_devices function where
  it has combo device for ringtone playback and hence it does not set
  asrc mode.

 -Invoke check_and_set_asrc_mode API from enable_snd_device where
  combo device is split.
