hwc: Add support for virtual displays
Add support for virtual displays in hwc.
The availability is detected when a valid list first appears.
Need a valid framebuffer handle to configure writeback based
on aligned dimensions.
Force full GLES virtual layers to go through HWC based on
boardconfig flag.

hwc: Add assertive display support.
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.
