Background: On MDP compositon, MDP keeps reading contents from the
pipes even on Idle Screen i.e. even when HWC is not queueing any new
buffers to MDP. Above data traffic leads to high power consumption.
Implementation: This change introduces a timer in HWC which will
timeout if there are no updates in bypass composition path for
the period specified via debug.bypass.idletime. Also SurfaceFlinger
will be notified to redraw the current frame which will be composed
into FB.

The current composition bypass implementation prevents the app frame rate from
being decoupled with vsync. As a result when a graphics application requests
EGL swap interval zero it is still limited by vsync. This change disables
composition bypass if any layers being composited for the frame are in
asynchronous mode.

Add support for external-only display. Layer buffers
marked with GRALLOC_USAGE_EXTERNAL_ONLY will be
displayed on external panel only, if available.
In addition if the layer buffer also has the flag
GRALLOC_USAGE_EXTERNAL_BLOCK then only that layer
will be displayed on external (During suspend).
When this mode is on, the default mirror mode for
external is stopped.

This change allows 3 or less layer use cases to get bypassed completely via MDP pipes.
If more than 3 layers, all of them gets composited on FB.
Intended FB fallback cases:
1) 4 or more layers
2) Any MDP pipe is in use
3) Any layer needs rotation
4) Any layer is allocated from non-pmem

This is a helper function that will return false if the given format is
supported by adreno drivers but not supported in GPU HW. For these
formats, adreno will use software color conversion routines to convert
them to acceptable format by the GPU HW. This may be required if we
want to avoid creating texture for certain formats when not absolutely
necessary. Could be defaulted to return true depending on a compile
time flag.
