description:
experimental IMX6SX support:
- add options SOC_IMX6SX
- add imx6sxccm device

tested on a UDOO Neo Full board.
known to work:
- uart (console)
- sdmmc0
- ethernet (enet0)

known to not work:
- USB (device not detected).

needs a modified device tree at this time (add arm,cortex-a9-twd-timer entry
copied from the imx6qdl dtsi); for unkown reason the imx6sx.dtsi file lacks
an entry for the a9ptmr although it is present in the soc (and, from what I
understood, in all cortex A9 SoCs).
