FM: make correct sequence of slimbus and audio port

 -in case of fm on sequence
   1. enable slimbus.
   2. open port at audio side.
   3. enable fm receiver.

 -in case of other than fm on scenarios where fm
  receiver is already enabled and audio
  path needs to start.
   1. open port at audio side.
   2. enable slimbus.

 -in case of other than fm on scenarios where fm
  receiver is already enabled and audio
  path needs to stop.
  1. disable slimbus
  2. close port at audio side.
