This is a followup patch for: https://lkml.org/lkml/2017/10/11/375

Make the struct config_item_type *type function argument of functions
config_{item/group}_init_type_name const as the argument in both the
functions is only stored in the ci_type field of a config_item structure
which is const.
Make the argument of configfs_register_default_group const as it is
only passed to the argument of the function config_group_init_type_name
which is now const.

This change allows lots of config_item_type structure to be const.
