dream in staging: remove wakelock support

From: Pavel Machek
Date: Thu Oct 22 2009 - 05:04:29 EST


Includes changed so that <linux/sched.h> is now needed for
TASK_INTERRUPTIBLE and friends, so include it.

Remove hooks for features not in mainline, such as earlysuspend and
wakelocks.

Signed-off-by: Pavel Machek <pavel@xxxxxx>
