Koen Vandeputte 3b4241071d imx6: disable UART dma 
Fixes these prints on boot:

[   13.785600] imx-uart 2020000.serial: DMA transaction error.
[   13.793134] imx-uart 2020000.serial: DMA transaction error.
[   13.798721] imx-uart 2020000.serial: DMA transaction error.

Based on following upstream patch by Tim Harvey (Gateworks):

80a01b6582

TX complete DMA messages are getting missed.
This is also currently an issue in mainline.
For now we will disable DMA in serial/imx.c.

This resolves an issue encountered with RS485 transmit.
