- Add chip macro for driver
- Modify 'IDLE_THREAD_STACK_SIZE' to 512
- Modify 'HWTIMER' to 'CLOCK_TIMER'
- Use 'clang-format' format driver and BSP code
- Fix SPI clock division configuration

**为什么提交这份PR (why to submit this PR)**
1. hc32驱动函数和rtt函数声明之间的参数类型不一致，在mdk编译时产生警告。
2. hc32的can设备，在注册时就把can中断使能了。导致can设备在打开前，就会产生中断。
3. hc32的pwm驱动，不支持PWM_CMD_SET_PERIOD和PWM_CMD_SET_PULSE指令，导致rt_pwm_set_pulse()函数返回失败。
**你的解决方案是什么 (what is your solution)**
1. 修改hc32驱动函数参数类型和声明一致。
2. 注册can设备时主动禁止can中断，因为打开设备时会主动打开中断。
3. 修改pwm驱动，增加PWM_CMD_SET_PERIOD和PWM_CMD_SET_PULSE指令支持。[errno code][-RT_ERROR] fix that use RT_ERROR without -2023-03-20T04:06:16ZMeco Man920369182@qq.com2023-03-17T04:12:16Zurn:sha1:0f461e870c481a24ce2690cca1949706bb80f9e7[errno code][-RT_EINVAL] fix that use RT_EINVAL without -2023-03-17T00:21:43ZMeco Man920369182@qq.com2023-03-16T04:44:05Zurn:sha1:dfddd79b2453ab13d12b69c7db14e2f685175af7[CAN]update struct can_filter_item and rt_can_msg (#6556)2022-11-22T02:45:51Zwdfk-prog1425075683@qq.com2022-11-22T02:45:51Zurn:sha1:569e2ae1e8671bdb17b3fa7b4197fdff6ad5cf1d
* 修改ry命令，已便于自定义保存路径
* modified: components/utilities/ymodem/ry_sy.c
* 修复从被动错误恢复后发送返回异常
* 修复在自动重传模式下,ACK异常阻塞线程
- 删除TX中断函数else分支。仅当RQCP位 置一才进入该中断
- 添加SCE中断函数中关于ACK_ERR的else判断。自动重传模式下会进入该判断,打断自动重传释放完成量。
* 增加对于CAN1与CAN2的SCE中断和TX中断的公共处理函数
* formatting格式化代码
* update struct can_filter_item and rt_can_msg
1. 对过滤器号和索引号结构体定义中同一名称hdr进行重命名hdr_bank和hdr_index,
以便准确区分.采用宏定义兼容以前变量名.
2. 添加接收标识rxfifo,已指明是哪个RXFIFO.
* 更正42M下的波特率
* 修复接收获取索引号错误
* 添加接收标识
* 更新注释
* 取消CANFD限制
* update struct can_filter_item and rt_can_msg
