ARM: dts: exynos: Add samsung,asv-bin property to Odroid XU3 Lite

The Exynos5422 SoC used on Odroid XU3 Lite boards belongs to a special
ASV bin but this information cannot be read from the Chip ID block
registers. Add samsung,asv-bin property for XU3 Lite to ensure the ASV
bin is properly determined.
