audio: Fix submix output device check.

-AUDIO_DEVICE_IN_FM_RX is incorrectly matched
 with AUDIO_DEVICE_OUT_REMOTE_SUBMIX because
 method audio_is_remote_submix_device is not
 checking for AUDIO_DEVICE_BIT_IN.

-Fix is to add AUDIO_DEVICE_BIT_IN while doing
 the check for AUDIO_DEVICE_OUT_REMOTE_SUBMIX.
