[BUG] A HARDFAIL occurred when running the up_rtc_settime function in stm32_rtcounter.c

### Description / Steps to reproduce the issue

1. Using the STM32F103 chip. When running to the function up_rtc_settime in the file stm32_rtcounter.c located in platforms/nuttx/NuttX/nuttx/arch/arm/src/stm32, the function encountered a hard failure.
2. In the function up_rtc_settime, the line putreg16(RTC_MAGIC, RTC_MAGIC_TIME_SET);, RTC_MAGIC_TIME_SET should be a register address, but currently it is a default illegal address: #define CONFIG_STM32_RTC_MAGIC_TIME_SET (0xf00d)
3. Currently, it has been found that this address cannot be modified even on the STM32F1 chip.
