Audio: out_open_pcm_devices - use out->config instead of pcm_device->pcm_profile->config.

Current get_pcm_device return always first finded pcm_profile.
And out->pcm_dev_list always have only pcm_device_playback pcm_profiles.

But if we need use deep_buffer pcm device
we need use deep_bufer pcm_config - current hal
don't did this...

And we configure out->config in adev_open_output_stream
function with proper pcm_config (deep or no).
