问题：
在使用硬件 I2C 驱动进行音频模块 WM8978 配置时，发现连续 rt_i2c_transfer 进行 I2C 传输时发现，连续多次调用 rt_i2c_transfer 会出现丢包现象；溯源发现是每次使用 rt_i2c_transfer 传输2字节，传输频率过高导致底层 HAL_I2C_Master_Seq_Transmit_DMA 报错 HAL_BUSY；

现象：
rt_completion_wait超时等待完成之后，I2C仍处于HAL_I2C_STATE_BUSY_TX状态，且后续第二次运行至HAL_I2C_Master_Seq_Transmit_DMA时会直接返回HAL_BUSY，从而直接 goto out; 退出而不会再次进行超时等待；

* drv_hard_i2c.c: 修复325行缺失'}'语法错误;更改HAL_I2C_xx_Transimt_xx调用中目标设备地址值;i2c_hard_config.h: 添加STM32F系列芯片xx_DMA_CONFIG宏定义;

* 回溯I2C设备地址传参处(msg->addr<<1)修改；

* fixup: 增加硬件I2C传输延时，解决连续传输导致HAL_BUSY状态；
