This patch adds support for a chunk heap that allows for buffers
that are made up of a list of fixed size chunks taken from a CMA.
Chunk sizes are configuratd when the heaps are created.

d function
implemented from exporter.
That helps to show exporter detail information.
For example, ION may show the buffer flag, heap name,
or the name of process to request allocation.
