"struct devlink_dpipe_table_ops" only contains some function pointers.
Update "struct devlink_dpipe_table" and the 'table_ops' parameter of
devl_dpipe_table_register() so that structures in drivers can be
constified.
Constifying these structures will move some data to a read-only section, so
increase overall security.
