samsung/exynos5250: unify code
It turns out that the exynos5-common code previously imported from u-boot is not common code at all but very specific to the 5250 and not compatible with the 5450. Hence, unify the directories exynos5250 and exynos5-common. We will try to factor out common code while progressing with the 5450 port.
