mm/device-public-memory: device memory cache coherent with CPU v5
Platform with advance system bus (like CAPI or CCIX) allow device
memory to be accessible from CPU in a cache coherent fashion. Add
a new type of ZONE_DEVICE to represent such memory. The use case
are the same as for the un-addressable device memory but without
all the corners cases.
Changed since v4:
- added memory cgroup change to this patch
Changed since v3:
- s/public/public (going back)
Changed since v2:
- s/public/public
- add proper include in migrate.c and drop useless #if/#endif
Changed since v1:
- Kconfig and #if/#else cleanup
