RT_Thread Studio创建工程编译时出错

```
error: ‘struct serial_configure‘ has no member named ‘flowcontrol‘
```

我的解决办法是如下，
定位结构位置在`serial.h`

```c
struct serial_configure
{
    rt_uint32_t baud_rate;

rt_uint32_t data_bits               :4;
    rt_uint32_t stop_bits               :2;
    rt_uint32_t parity                  :2;
    rt_uint32_t bit_order               :1;
    rt_uint32_t invert                  :1;
    rt_uint32_t bufsz                   :16;
    rt_uint32_t reserved                :4;//默认保留为6位，这里修改为4位
    rt_uint32_t  flowcontrol            :2;//为flowcontrol 分配2位
};
```

重新定义

```c
#define  RT_SERIAL_FLOWCONTROL_NONE     0x00
#define  RT_SERIAL_FLOWCONTROL_CTSRTS   0x01
```

编译无误。

不知道这样改有没有问题，希望大神指导下！
