staging: android-alarm: Switch from wakelocks to wakeup sources

In their current AOSP tree, the Android in-kernel wakelock
infrastructure has been reimplemented in terms of wakeup
sources:
http://git.linaro.org/gitweb?p=people/jstultz/android.git;a=commitdiff;h=e9911f4efdc55af703b8b3bb8c839e6f5dd173bb

The Android alarm driver currently has stubbed out calls
to wakelock functionality. So this patch simply converts
the stubbed out wakelock calls to wakeup source calls, and
removes the empty wakelock macros

Greg, would you mind queuing this in staging-next?

Staging: android: Alarm driver cleanups

Little cleanups. Enum value ANDROID_ALARM_TYPE_COUNT was treated as
an alarm type within a switch statement. That condition was unreachable
though.

staging: alarm-dev: Drop pre Android 1.0 _OLD ioctls

Per Colin's comment:
"The "support old userspace code" comment for those two ioctls has
been there since pre-Android 1.0.  Those apis are not exposed to
Android apps, I don't see any problem deleting them."

Thus this patch removes the ANDROID_ALARM_SET_OLD and
ANDROID_ALARM_SET_AND_WAIT_OLD ioctl compatability
logic.
