   * @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
