Add basic support for mini2440 dev board.
This work is mainly based on a9m2440 board implementation from Juergen Beisert <jbe@pengutronix.de>. Functionality was tested only running barebox from ram. Loading to flash and booting will not work because missing lowlevel_init functionality (lack of jtag debugger on my side ;)).
