Dirk Behme a2c718ce6a serial: imx: disable TDMAEN in imx_flush_buffer()
Terminating the DMA, make sure the interrupt is disabled, too.
This fixes random kernel Oops due to dma_tx_call() called for
invalid transmissions.

If we disable the TDMAEN, make sure it's enabled again if a TX
DMA is started.
