This patch is to add the machine descriptions for ODROID-XU3/4 boards
in order to present the hardware name at /proc/cputinfo rather than
"SAMSUNG EXYNOS (Flattened Device Tree)". An embedded open source project,
such as DietPi, reads the hardware name to run different features.

        $ cat /proc/cpuinfo | grep Hardware
        Hardware        : ODROID-XU4
