Huang Shijie a5919442bc serial: mxs-auart: disable the Receive Timeout Interrupt when DMA is enabled
When the DMA is enabled, the Receive Timeout interrupt is very easy to be arised
in the 3M baud rate.  The interrupt handler (aka mxs_auart_irq_handle) will call
mxs_auart_rx_chars() to handle the received data. This is not right, we can not
get the correct data from the RXFIFO now, the data have been moved to the
DMA buffer by the DMA engine.

This patch
  (1) disables the Receive Timeout Interrupt when the DMA is enabled,
  (2) and invoke the mxs_auart_rx_chars() only when the DMA is not enabled.
