This commit adds a new defconfig to build a X-based
graphical system for the Minnowboard MAX board.
* The 'openbox' windows manager is chosen because it's simple
and lightweigth.
* Basic X apps are enabled (such as xrandr, xterm), so we
can at least get a console and change video mode.
* ALSA default configuration is provided, so HDMI audio
works out-of-the-box.
* OpenGL is supported.
Tested on Minnoboard Turot (which is Minnowboard Max compatible).
