ARM: rename boards to more consistent naming
This renames the Freescale and Phytec board directories and defconfig files to a common naming scheme. The board directories are named <vendor>-<board> and the defconfig files are named <vendor>-<board>_defconfig. Also the DataModul realq7 is renamed to its Marketing Name eDM-QMX6.
