Subject: [PATCH] Triggering EarlySuspend based on BackLight brightness

EarlySuspend is triggered currently based on just timeout. Due to this,
backlight brightness is not coming down to zero.

Change-Id: If89ec6650308109630dbb7ee1be0b96df4ed3534
CRs-Fixed: 381087

Allowing display turning off animation before Early suspend.

This change passes display turning off information to
animation call so that display off animation can be played
before early suspend call.
Reverted two and three changes in the below list with this patch.
Changes introduced in previous patch were:
1.Send early suspend call after display baclklight off
2.All animations off once display goes to dim.
3.Removed duration to turn off screen as i don't see this in ICS.
