Subject: [PATCH] Add wakelock to audio HAL. Bug 2218158.

Applications are supposed to hold a wakelock. However, since 1.0,
the audio driver and/or HAL has held a partial wakelock. That means
that many apps will be broken if we don't hold a wakelock while
audio is playing. This patch holds a wakelock while the audio
driver is open and releases it when it goes to standby mode.
