David Sidrane 6c186b6084 stm32h7:serial make TX DMA busy when there are an outstanding transaction
If a TX DMA completion interrups a forground write.
    The TX DMA completion can start a dma_send and it will
    then followed by the forground write's dma_send
    stoping the,then in progress DMA.

    By atomicaly marking the tx dma busy, the forground
    write will not perform the dma_send, and will only
    enqueue the data. At the next TX dma completion any
    data pending in the tx queue will be sent
