alsa_sound: Maintain separate mute states for each call type.

   Mute is not proapagated to CS call session during
   SRVCC handover.

   This is due to mute state is not updated to CS call
   session when SRVCC handover happens.

   Fix is to maintain different mute states to different
   call types, so that mute state will be updated on
   each call type independently.

alsa_sound: primary desc check for sonification

- Audio glitches on alarm expiry if alarm starts
  on screen lock/standby mode

- On alarm expiry alarm tone will start play on combo device
  &screen unlock tone try to play on headset which results
  multiple device switch, as a result audio glitches are audible

- If sonfication strategy is used by primary desc , we will
  treat all non music streams with sonfication stragey which
  will avoid device switch

alsa_sound:  Fix to avoid crash while erasing item from mDeviceList

-In AudioHardwareALSA's destructor,while erasing item from mDeviceList
is leading to crash in current implementation, if List containing
more than one item.
-This is happening because of Invalid iterator value after deleting
current item from List, then using same iterator for next operation.
-It can avoid returning an Iterator item form List's erase function
and then use it for next operation.

alsa_sound: Fix Echo reference logic

-During Skype call , there is Echo hearing at far end device.
-This is happening because Echo reference is setting after enabling
 the devices, so a wrong EC reference id is sending to DSP.
-Echo reference should be set even before enabling the devices.

  alsa_sound: Fix for voice volume restore after reboot

  - Maximum volume is heard for call after reboot even if it
    was set to minimum during the last call before reboot.

  - During call after reboot, mLastvoiceVolume is getting
    updated improperly and hence proper volume is not
    being applied.

  - Fix is to cache the voice Volume properly.
