base/node: Use 'property' to identify an access parameter

Usage of 'attr' and 'name' in the context of a sysfs attribute
definition are confusing because those read as being related to:

	struct attribute .name

Rename 'name' to 'property' in preparation for renaming 'struct
node_hmem_attr' to a more generic name that can be used in more contexts
('struct access_coordinate'), and not be confused with 'struct
attribute'.
