seccure. This is required for use cases such as secure playback when
AD is enabled.

Do not create a writeback instance during dumpsys.
Instead use the dumpsys to return empty if no instance exists.
This fixes the issue where
a) Unnecessary instance is created.
b) Dumpsys has garbage, if a valid instance didn't exist

On systems that do not have a Contiguous Memory Allocator (CMA) it is
the responsibily of the client to specify the required address alignment.
Additionally, we centralize size alignment to so that overlay clients
do not need to take of this.

In the writeback path, when memory is allocated and managed by

request is for a secure allocation

Add assertive display support to hwc. This feature takes effect when
node /sys/class/graphics/fb*/ad is present. This signifies that that LM0
is being used with fb* for writeback.
When a video playback begins we write "1" to this node to indicate to
post processing that a writeback will happen. Likewise a "0" is written
to this node when playback stops.
The original contents are worked upon and the modified output is fed
via writeback to either rotator or mdp as appropriate.
The feature doesnt trigger when either:
1) Buffer size exceeds 2048
2) External display is connected
3) Multiple yuv streams are present
When this mode is active, MDP comp is applied only to yuv layer.
