 * Mark function as DDE kit initcall
 *
 * \param fn     function name
 * \param id     identifier to distinguish multiple calls to 'fn'
 *
 * The initcall function must comply 'int func(void)'.
 * The marked function is exported via a non-static symbol called
 * "dde_kit_initcall_<id>_<fn>". On driver startup, the driver environment has
 * to explicitly call these functions.
 *
 * This is the right mechanism to mark, e.g., Linux module_init() functions.
