David Jander 907eda32a3 Revert "serial: imx: initialized DMA w/o HW flow enabled" ...

This reverts commit 068500e08d.

According to some tests, SDMA support is broken at least for i.MX6 without
HW flow control. Different forms of data-corruption appear either with
the ROM firmware for the SDMA controller as well as when loading Freescale
provided SDMA firmware versions 1.1 or 3.1.
