RT-Thread中AT32F403A使用RTC
RT-Thread Studio中开启RTC，根据官方说明（基于STM32），只要三步：搜索
/** if you want to use rtc(hardware) you can use the following instructions.
*
* STEP 1, open rtc driver framework(hardware) support in the RT-Thread Settings file
*
* STEP 2, define macro related to the rtc
* such as BSP_USING_ONCHIP_RTC
*
* STEP 3, modify your stm32xxxx_hal_config.h file to support rtc peripherals. define macro related to the peripherals
* such as #define HAL_RTC_MODULE_ENABLED
但是第三步，需要在hal_config.h文件中修改，而AT32用的是STD库，没有这个文件，需要在哪里进行修改？
