YangZhongQing 1c2d05d545 RTC STM32F1 Enable PWR and BKP clocks in the same time 
bsp\stm32\libraries\HAL_Drivers\drv_rtc.c在STM32F10x上有一个“RTC首次上电时BKP时钟没使能”的问题。

STM32F10x要求：
写RTC Domain and RTC registers之前需要__HAL_RCC_BKP_CLK_ENABLE（详见：stm32f1xx_hal_rtc.c里面的##### Backup Domain Access #####）

问题分析：
1、RTC首次上电时：由于HAL_RTC_Init初始化之前没有使能BKP时钟，所以对RTC registers的初始化无效。
2、然后用date命令设置时间，调用到set_rtc_time_stamp也没有__HAL_RCC_BKP_CLK_ENABLE，所以HAL_RTCEx_BKUPWrite写的值无法真正永存于BKP，重启后就丢失。
最终导致：对于RTC首次上电的情况，每次重启后RTC_BKP_DR1里的值都不是BKUP_REG_DATA，导致永远无法调用到rt_rtc_f1_bkp_update()去使能BKP时钟。

解决办法：
参考STM32F10x_StdPeriph_Lib_V3.5.0\Project\STM32F10x_StdPeriph_Examples\RTC\Calendar\main.c里面的RTC_Configuration()同时打开RCC_APB1Periph_PWR和RCC_APB1Periph_BKP
