libnvdimm: Move attribute groups to device type
Statically initialize the attribute groups for each libnvdimm device_type. This is a preparation step for removing unnecessary exports of attributes that can be included in the device_type by default. Also take the opportunity to mark 'struct device_type' instances const.
