libnvdimm: Move nvdimm_bus_attribute_group to device_type

Browse Source 
A 'struct device_type' instance can carry default attributes for the
device. Use this facility to remove the export of
nvdimm_bus_attribute_group and put the responsibility on the core rather
than leaf implementations to define this attribute.
