After i tested the DMA for uart with the Bluetooth. I found several small
places need to be fixed.

The patch set contains several fixes for the DMA support.

  serial: imx: implement the flush_buffer hook
  serial: imx: check the DMA for imx_tx_empty
  serial: imx: fix the wrong number of scatterlist entries when
    xmit->head is 0
  serial: imx: use the dmaengine_tx_status
