Dear Sascha, I think these patches deliver simpler end result and are more complete than what you just posted. In particular, the serial: imx: set_mctrl(): correctly restore autoRTS state addresses exactly the issue your patch is about, but in a slightly simpler manner. The patches are not tested yet, so I've put RFC in the header. Just my 2 cents. I can obviously re-roll them on top of your work later, if required.
