sh: Shuffle the board directories in to mach groups.
This flattens out the board directories in to individual mach groups, we will use this for getting rid of unneeded directories, simplifying the build system, and becoming more coherent with the refactored arch/sh/include topology. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
