All hardware drivers should allocate IOVA-contiguous
memzones for their hardware resources.
Signed-off-by: Anatoly Burakov <anatoly.burakov@intel.com>

Notes:
v4:
- Use new memzone flag instead of new API
- Remove experimental API from build files
v3:
- Add experimental API to build files
v3:
- Moved patch earlier in the patchset
- Allowed experimental API in the build system
