msm7x30: Fix routing for all AudioSessionOut types

 * Pass the new output device around so that we're not always just using
   the one in the base class. This was preventing proper routing for
   all output streams.

audio/msm7630: Add latency support for LPA

-Audio loss for few seconds on headset connection.
-Stream is unmute in checkDeviceMuteStrategies before device switch
occurs.
-Increase delay in tempMute to ensure unmuting happens after device
switch happens. Also change latency for LPA to correct value similar
to that of hpcm.

audio/msm7630 : Stability issue with LPA play back.

- ANR is observed during LPA playback when there is song switch for
  every few seconds
- The song switch does not happen when the song is played till the end
- Native crashes are observed during rapid seek, next and previous
  song switch operations. There is some race condition between write and
  flush which results in adding a buffer multiple times to empty queue.
  This tries to free the buffer multiple times during reset and results
  in native crash. Fix this issue by adding proper mutex in write and
  flush calls which synchronizes these operations and avoids crashes.
  After Pausetimeout, reset is called due to which EOS is posted
  to observer. This results in start or reset operation on a closed
  sink leading to crashes. Avoid posting EOS if reset is already
  called.

Revert "msm7x30: Update device API"

 * Causes some routing issues, for example when using GEL
   and listening to music via headset, audio is routed to
   speaker when jumping to home screen from Apollo. Probably
   missing some additional changes, so revert this for now.

This reverts commit 75afa6a8a1a928f861280b640222f35e64929995.
