 * @par Description:
 * This API is used to register a startup module to the startup process.
 *
 * @attention
 * <ul>
 * <li>Register a new module in the boot process of the kernel as part of the kernel capability component.</li>
 * <li>In the startup framework, within the same _level, the startup sequence is sorted by
 * the registered function name </li>
 * <li>If the registration is not accompanied by the startup process after calling this interface,
 * try to add -u_hook to liteos_tables_ldflags.mk </li>
 * </ul>
 *
 * @param  _hook    [IN] Type  #UINT32 (*)(VOID)    Register function.
 * @param  _level   [IN] Type  #UINT32              Init level in the kernel.
 *
 * @retval None
 * @par Dependency:
 * <ul><li>los_init.h: the header file that contains the API declaration.</li></ul>
