UART_FLAG_TC 不能在中断里CLEAR;
因为函数 static int stm32_putc(struct rt_serial_device *serial, char c)里发送完成后
while 循环等这个标志退出，中断服务函数CLEAR后，此处进入死循环

增加ROMFS，FATFS和未来的LittleFS将挂载在ROMFS上
初步增加littlefs文件系统，尚未完全实现一键化配置

* Add CANFD support and correct typos

- Added CANFD required fields to can.h
- Fixed typos in can.h and can.c
- Corrected all the projects affected by the typo
- Fixed wrong line-ending in some affected can driver files
