armv7: Move Exynos from 'cpu' to 'soc'.

The Exynos family and most ARM products are SoC, not just CPU.

We used to put ARM code in src/cpu to avoid polluting the code base for what was
essentially an experiment at the time. Now that it's past the experimental phase
and we're going to see more SoCs (including intel/baytrail) in coreboot.
