Jérôme Glisse 858b54dabf mm/hmm/devmem: dummy HMM device for ZONE_DEVICE memory
This introduce a dummy HMM device class so device driver can use it to
create hmm_device for the sole purpose of registering device memory.  It
is useful to device driver that want to manage multiple physical device
memory under same struct device umbrella.
