GD32 OTA/Bootloader驱动函数

驱动函数需要修改一个文件rt_fota.c，添加内部flash操作相关文件，删除外部flash操作相关文件，移植过程注意事项及其它外设移植细节参见移植完整版RT-Thread到GD32F4XX(详细) 中关于bootloader及flash移植相关内容，移植完成后使用及验证方法同stm32

原开源项目位于https://gitee.com/spunky_973/rt-fota，只适配了stm32f4系列，未实现hash校验；本博客所做改动仅为适配GD32F4XX系列，及添加了hash校验（已提交PR），同时修改片外升级为片内升级，进一步缩小bootloader大小，开源地址为https://gitee.com/yangfei_addoil/rt-fota-gd32
