[PATCH 1/5] mm/persistent-memory: match IORES_DESC name and enum memory_type one

[Jérôme Glisse]

Use consistent name between IORES_DESC and enum memory_type, rename
MEMORY_DEVICE_PUBLIC to MEMORY_DEVICE_PERSISTENT. This is to free up
the public name for CDM (cache coherent device memory) for which the
term public is a better match.
