ARM: exynos_defconfig: Increase CONFIG_CMA_SIZE_MBYTES to 96
Current CMA size of 64 Mbytes is right on the edge of being small when several drivers need to allocate large CMA buffers. For example, if the s5p-mfc driver needs to pre-allocate CMA memory to decode a H.264 1080p video, then there won't be enough CMA memory left for other drivers, such as the exynos-drm driver that may need to allocate GEM buffers for the display manager. Increasing CMA size to 96 Mbytes in exynos_defconfig addresses use-cases such as these.
