[RFC PATCH 2/2] xen/grant-table: Use unpopulated DMAable pages instead of real RAM ones

From: Oleksandr Tyshchenko Depends on CONFIG_XEN_UNPOPULATED_ALLOC. If enabled then unpopulated DMAable (contiguous) pages will be allocated for grant mapping into instead of ballooning out real RAM pages. TODO: Fallback to real RAM pages if xen_alloc_unpopulated_dma_pages() fails.
