xen/grant-dma-ops: Add option to restrict memory access under Xen
Introduce Xen grant DMA-mapping layer which contains special DMA-mapping
routines for providing grant references as DMA addresses to be used by
frontends (e.g. virtio) in Xen guests.
Add the needed functionality by providing a special set of DMA ops
handling the needed grant operations for the I/O pages.
The subsequent commit will introduce the use case for xen-grant DMA ops
layer to enable using virtio devices in Xen guests in a safe manner.
