Subject: [PATCH] ARM: exynos_defconfig: Enable zram as loadable modules

Enable zram and dependencies as loadable modules. This allows to use the
/dev/zramX virtual block devices as swap stored in system memory.

Options were taken from commit 5c824e8be64d ("ARM: omap2plus_defconfig:
Enable zram as loadable modules") that does the same for OMAP2+ platforms.
