Current CMA size of 64 Mbytes is right on the edge of being too small
for some display managers.  With the proposed s5p_mfc patch series that
pre-allocate buffers, when display manager starts, it fails to get GEM
buffers.  Increasing the CMA size to 96 solves the problem.

Change CONFIG_CMA_SIZE_MBYTES to 96 in exynos_defconfig to address the
problem.
