Description: Allow allocating DMA capable buffers with grant reference module

More info: Extends grant table module API to allow allocating DMA capable buffers and mapping foreign grant references on top of it. The resulting buffer is similar to one allocated by the balloon driver in that proper memory reservation is made by ({increase|decrease}_reservation and VA mappings are updated if needed). This is useful for sharing foreign buffers with HW drivers which cannot work with scattered buffers provided by the balloon driver, but require DMAable memory instead.
