ARM: sunxi_defconfig: Enable CMA
The DRM driver most notably, but also out of tree drivers (for now) like the VPU or GPU drivers, are quite big consumers of large, contiguous memory buffers. However, the sunxi_defconfig doesn't enable CMA in order to mitigate that, which makes them almost unusable. Enable it to make sure it somewhat works.
