These APIs can be used to register/unregister regions
of pinned, huge page memory that are separate from
huge page memory allocated by the default DPDK
allocations. These APIs will be used by an upcoming
SPDK vhost-scsi target to enable SPDK to target
NVMe DMA operations directly to VM memory that has
been allocated by QEMU using pinned huge pages.
