* @brief Register a startup module to the startup process.
*
* @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>
