serial: mxs-auart: add the DMA support for mx28
Only we meet the following conditions, we can enable the DMA support for
auart:
(1) We enable the DMA support in the dts file, such as
arch/arm/boot/dts/imx28.dtsi.
(2) We enable the hardware flow control.
(3) We use the mx28, not the mx23. Due to hardware bug(see errata: 2836),
we can not add the DMA support to mx23.
