* 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。
