* 本次提交包括①BSP驱动新增②F103库更新③GCC、IAR适配及MDK更新④README文件及由更新驱动引起的脚本改动。 详情如下： 一、BSP驱动新增 这是本次PR的主要目的，现新增了如下BSP驱动： ADC、DAC、RTC、PWM、HWTIMER、I2C、SPI和WDT等八个驱动文件。 二、F103库更新： 本次提交使用2022年3月初极海官网发布的最新F103库，主要增加了版权声明、USB驱动及其他代码调整。 三、编译器适配： 1、新增GCC编译支持，在ENV工具下编译能成功且输出的bin文件能够使开发板闪灯。 2、新增IAR工程支持。 3、由F103的SDK更新，MDK的工程也进行了相应更新。 四、其他 1、README文件做了修改，加入了scons编译后的jlink下载说明和官网链接。 2、Kconfig、SConscript脚本根据驱动更新做了修改。 * 格式化代码（AStyle + Formatting） * 增加BSP APM版权声明 * 在ci添加当前bsp的路径，以能够验证gcc能否正常编译 * 路径的“\”改为“/”
