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.

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.
