[Feature] I2C驱动框架的rt_i2c_control函数，V5.2.2版本看是没有获取设备锁，那是不是意味着要修改速率的时候，必须保证I2C是停止状态。

Describe problem solved by the proposed feature

rt_err_t rt_i2c_control(struct rt_i2c_bus_device *bus,
int cmd,
void *args)
{
rt_err_t ret;

if(bus->ops->i2c_bus_control)
{
    ret = bus->ops->i2c_bus_control(bus, cmd, args);
    return ret;
}
else
{
    LOG_E("I2C bus operation not supported");
    return -RT_EINVAL;
}

Start at rt_i2c_control and trace the bus->ops->i2c_bus_control implementation in the I2C driver framework. Determine how device locking interacts with changing the I2C rate and define the expected behavior for an active bus; done should include a focused implementation or documented resolution with tests where the framework supports them.
