The specification for GRALLOC_USAGE_PROTECTED indicates that
allocations with that flag must be protected by securing with
hardware. If such protection is not possible, the buffer must not
be composited. In our current software only the MM_HEAP is
secured. If we allocate protected buffers from any other heap we
block those from being displayed.

This changes GRALLOC_USAGE_PRIVATE_CAMERA_HEAP to
GRALLOC_USAGE_PRIVATE_ADSP_HEAP as the CAMERA_HEAP
is not used anymore

libadreno_utils.so is an adreno utility library. It computes the
optimal stride required for a surface of a particular width and
bpp. Using this computed stride allows us to efficiently use the
dual memory channels and increase performance.
Currently the utility library only computes the optimal stride
for RGB surfaces.

- Introduce a new class to Get the Adreno computed stride information.
This class has been added to allow adreno library computed strides to
be propagated to the allocation function as well as those clients
requesting it.
- Add a new Perform function to get the stride. The width and the format
can be passed from the calling functions (like EGL) to get the stride of
the buffer.

The GRALLOC_USAGE_PROTECTED flag is being used for non TZ DRM
if non contiguous heaps such as IOMMU are used. Hence do not
set the ION_SECURE flag for such heaps as they cannot be secured
through trustzone.

For secure content, use GRALLOC_USAGE_PROTECTED flag instead of
the obsolete flag GRALLOC_USAGE_PRIVATE_CP_BUFFER.

Venus color format is not supported on older platforms. Add target
specific flag in display hal and define Venus macros to zero for
older platforms.
