policy_hal: remove unused function isVirtualInputDevice 

- isVirtualInputDevice is a static member function and
  its implementation should be modified in base class only.
- Remove isVirtualInputDevice in policy_hal and modify
  APM_AUDIO_IN_DEVICE_VIRTUAL_ALL in base class to support
  FM recording over A2DP headset.
