Changpeng Liu 4ec3ed5b94 nvmf/vfio-user: add migration region mmio registers 
The miration region data structure is from `vfio_device_migration_info`
defined in `linux/vfio.h`, `vfio_device_migration_info` is in the 0th
offset of the VFIO_REGION_SUBTYPE_MIGRATION region, and in vfio-user,
we reserve first one page of BAR9 for this MMIO accesses.

libvfio-user already helps us to hide some implementation details
based on vfio migration specification, here we just use the two
fields to help the migration process.
