Adding Beagleboard support - unfinished

The beagleboard target is still unfinied: running: - MMC Card (incl. boot) - DSS2 graphic driver missing: - full USB Host and Gadget TODO: - improve graphic support - full boot from flash and SD - incl. update - XServer - Gaming support git-svn-id: svn://svn.openwrt.org/openwrt/trunk@18775 3c298f89-4303-0410-b956-a3cf2f4a3e73
