cm-t35: move cm-t35 to live in compulab directory
Currently the cm-t35 support code lives under board/cm_t35 directory. Some of the code can be shared with other/future CompuLab boards, so move the cm-t35 to live under board/compulab/cm_t35 directory. Signed-off-by: Igor Grinberg <grinberg@compulab.co.il> Tested-by: Nikita Kiryanov <nikita@compulab.co.il>
