* [RTduino]更新引脚分布

* update

* update readme

版本控制规范：https://semver.org/

目前的版本子号不是很规范，其中RT_VERSION甚至和VS那边造成了冲突
```c
/* RT-Thread version information */
#define RT_VERSION                      4L              /**< major version number */
#define RT_SUBVERSION                   1L              /**< minor version number */
#define RT_REVISION                     1L              /**< revise version number */
```

参考ESP32：
```c
/** Major version number (X.x.x) */
#define ESP_ARDUINO_VERSION_MAJOR   2
/** Minor version number (x.X.x) */
#define ESP_ARDUINO_VERSION_MINOR   0
/** Patch version number (x.x.X) */
#define ESP_ARDUINO_VERSION_PATCH   3
```

建议改成：
```c
/* Major version number (X.x.x) */
#define RT_VERSION_MAJOR   4
/* Minor version number (x.X.x) */
#define RT_VERSION_MINOR   2
/* Patch version number (x.x.X) */
#define RT_VERSION_PATCH   0
```

* [add] board/Kconfig 完善SPI3部分

 fix flexcan driver for imxrt1170

使用APM32F407VGT6芯片发现shell命令行无法接收命令，解决shell命令行输入问题

将board.c中的：
GPIO_ConfigStruct.mode = GPIO_MODE_IN;
GPIO_ConfigStruct.pupd = GPIO_PUPD_UP;
修改为：
GPIO_ConfigStruct.mode = GPIO_MODE_AF;
GPIO_ConfigStruct.pupd = GPIO_PUPD_NOPULL;

使用APM32F407VGT6测试成功

* 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

* add Kconfig file "USART2~USART8"

* 增加printf格式2进制和8进制，RT_KPRINTF_USING_LONGLONG 和 RT_PRINTF_SPECIAL 做了相应处理

* Update drv_usart.h

CH32V307的串口1外设是对接在APB2桥上，其他串口均对接在APB1桥上

已完全测试，并发现一个问题，已修正。

* add ignore files and directories

* 消除编译警告；修正板级配置信息

* [pwm]Improve the code

* 将与bsp无关的代码移植到框架部分

* 添加注释

修复 rt_spi_sendrecv16 api 对最高有效位(MSB or LSB)的处理不当造成的一些问题。
