ANDROID: staging: ion: move definition of attachment 



The ion_dma_buf_attachment definition that is connected
to attachment of ion_buffer is used by dma buf ops.
However this definition should be available for heap's
dma buf ops as well as for built-in dma buf ops.
Therefore we move this definition to the ion header.
