configs/olimex_a20_olinuxino_lime_mali_defconfig: new board
This commit adds a new defconfig for the Olimex A20 OLinuxino Lime board, based on the 3.4.x vendor specific kernel, which allows to use the Mali 3D acceleration for OpenGL support.

This is a open hardware board,

+The legacy linux-sunxi kernels are based on the vendor code drops.
+It is only useful when accelerated 3D graphics and multimedia support
+is strictly necessary.
+
+The Mainline Kernel is already a much better choice for a headless server.
+And also the mainline kernel works fine even for a basic Linux desktop
+system running on top of a simple framebuffer, which may be good enough for
+the users who do not need fancy 3D graphics or video playback acceleration.
