Allocate a dax_device to represent the capacity of a device-mapper instance. Provide a ->direct_access() method via the new dax_operations indirection that mirrors the functionality of the current direct_access support via block_device_operations. Once fs/dax.c has been converted to use dax_operations the old dm_blk_direct_access() will be removed. A new helper dm_dax_get_live_target() is introduced to separate some of the dm-specifics from the direct_access implementation. This enabling is only for the top-level dm representation to upper layers. Converting target direct_access implementations is deferred to a separate patch.
