pit: Create an exynos5420 directory which is nearly a copy of exynos5250.

This change creates an exynos5420 directory with code that will eventually
implement support for the exynos5420 cpu from Samsung. Currently it's a copy
of the exynos5250 directory with the name changed. There are going to be some
problems where headers in src/cpu/samsung/exynos-common include headers in the
exynos5250 directory directly.
