  1. s32k3xx:edma clear state before callback add idle check 

       This prevents dma stop operations called of a completion
   call back from rentering, the callback and ensures that
   the call back will see the idle state.

  2. s32k3xx:Serial refactor out tx dma semaphore 

      Fixes stuttering output.

  The use of the semaphore was causing blocking
  on non blocking callers. This ensured that
  the TX DAM would be restated, but when it
  was switched to trywait in 8362e31, it left
  data in the xmit queue unsent.

  This solution removes the semaphore and restart
  the DMA on completion if there is more data in
  the xmit queue to be sent.
