hal: Add option to use low latency as primary output

 * Google's original design uses the low latency output as primary for
   playback unless a series of checks are passed in the framework which
   would use deep buffer mode.  Qualcomm changed this long ago in order
   for usecases like AV which don't require low latency to be forced to
   use deep buffering. This has been a catastrophic failure ever since
   it was changed, causing crackles and pops randomly while playing
   notifications due to underruns. Either I am too stupid to make it
   work, or this behavior is fundamentally flawed.
 * Add a flag to do it Google's way, I'm tired of this bug.
