Revert "exynos5250/snow: deprecate time.h"
This reverts commit 2fde9668b47e74d1bfad2f1688a4481e6b966d04
Somehow this got merged before its dependencies. 3190 must be merged first, followed by 3176. However 3190 will fail while this patch is in. So the situation can't correct itself.
Reverting this until the other two go in.
