The DAX drivers were missing sysfs ABI documentation entirely. Add this missing documentation for the sysfs ABI for DAX regions and Dax devices in patch 1. Add a new ABI for toggling memmap_on_memory semantics in patch 2.
The missing ABI was spotted in [1], this series is a split of the new ABI additions behind the initial documentation creation.
