为什么提交这份PR (why to submit this PR)
serial_v2驱动框架，rt_serial_tx_enable()函数，在 DMA阻塞发送(RT_DEVICE_FLAG_DMA_TX and RT_SERIAL_TX_BLOCKING) 的时候，使用rt_malloc分配了tx_fifo内存，但是并未对tx_fifo->rb.buffer_ptr指针进行初始化（rt_malloc不会自动初始化内存），因此可能导致buffer_ptr是一个随机指针。但是rt_serail_write()函数需要根据tx_fifo->rb.buffer_ptr是否为RT_NULL来判断是调用_serial_fifo_tx_blocking_nbuf()还是_serial_fifo_tx_blocking_buf()。
由于tx_fifo->rb.buffer_ptr可能是一个随机值（不一定为RT_NULL=0），导致RT_DEVICE_FLAG_DMA_TX and RT_SERIAL_TX_BLOCKING模式下调用了_serial_fifo_tx_blocking_buf()，但是rb没有真正开辟内存空间，导致内存异常
你的解决方案是什么 (what is your solution)
rt_serial_tx_enable()，在DMA阻塞发送分支下，对tx_fifo->rb.buffer_ptr进行初始化，赋值为RT_NULL。[kernel][dm]适配新的设备驱动模型 (#8075)2023-10-18T12:50:30Zzms12345685141075+zmshahaha@users.noreply.github.com2023-10-18T12:50:30Zurn:sha1:d01dd05a0cd2107d85e26a445a43957880fd1978[debug] use LOG_D instead RT_DEBUG_LOG2023-07-28T17:50:32ZMeco Man920369182@qq.com2023-07-28T03:33:14Zurn:sha1:4e0225a48d59976b74f6e06cec64532ce00495ad
