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.
