FM might lose audio focus and go in the pause state. Hence request audio
focus during resume. Otherwise, activity displayed might be FM but audio
source might be something else like music.

In scenarios where FM has lost audio focus and FM service is running, we
end up enabling FM audio path when A2DP is disconnected. This results in
more than one audio source being played simultaneously. Enable FM audio
path only when FM has audio focus.

Everytime there is data activity, notch filter settings need to be
updated. This request gets queued and executed after a delay of 10
seconds. The update request might take 2 seconds in the worst case.

Data activity might change very rapidly resulting in large number of
RESET_NOTCH_FILTER messages being put queue before the first request
itself is processed. In such scenario, multiple requests are processed
together and they will take time to execute greater than ANR threashold
time.
