frameworks/base: Fix race conditions on resume/suspend using power key

The wakelock PowerManagerService.Display sometimes cannot be released
after two quick power key pressings like a double click during phone
sleep (the target will resume then supposedly suspend shortly).

The second key event disturbs display power state on resume, as a
result display resources won't get released on suspend, which is fixed
in this change.

audio: Fix for LPCM surround sound recording

 - Format WAVE was defined as 10, which is getting
 over-ridden by format THREE_GPP2 (which holds value 10),
 because of which Media recorder failed for LPCM SSR.
 - Fix this by defining format WAVE to 11.
