nvdimm: Use of_property_present() and of_property_read_bool()

Use of_property_present() and of_property_read_bool() to test
property presence and read boolean properties rather than
of_(find|get)_property(). This is part of a larger effort to remove
callers of of_find_property() and similar functions.
of_(find|get)_property() leak the DT struct property and data pointers
which is a problem for dynamically allocated nodes which may be freed.
