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.
