Tri Vo 8a6cc52ed7 Remove coredomain /dev access no longer needed after Treble
According to go/sedenials (internal dogfooding), coredomain access to
following types is not exercised and can be removed:
iio_device
radio_device
tee_device

Access to audio_device is still needed since some ALSA interfaces
(/dev/snd/*) are directly used by system_server.
