staging: android: ion: Get rid of map_dma/unmap_dma
The map_dma API interface was designed to generate an sg_table.
Currently, every client just creates the table at allocation time and
then returns the one table. Nothing happens on unmap_dma either.
Just get rid of the API and assign the sg_table directly.
