pmem: add dax_operations support
Setup a dax_device to have the same lifetime as the pmem block device and add a ->direct_access() method that is equivalent to pmem_direct_access(). Once fs/dax.c has been converted to use dax_operations the old pmem_direct_access() will be removed. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
