mm/hmm: add a helper function that fault pages and map them to a device
This is a all in one helper that fault pages in a range and map them to a
device so that every single device driver do not have to re-implement this
common pattern.
This is taken from ODP RDMA in preparation of ODP RDMA convertion. It
will be use by nouveau and other drivers.
