MX: set a common place to share code for Freescale i.MX
Up now only MX5 and MX6 can share code, because they have a common source directory in cpu/armv7. Other not armv7 i.MX can profit of the same shared code. Move these files into a directory accessible for all, similar to plat-mxc in linux. Signed-off-by: Stefano Babic <sbabic@denx.de>
