ARM: exynos: introduce EXYNOS_ATAGS symbol 

As a preparation for multiplatform support, this introduces
a new Kconfig symbol to split the ATAGS based EXYNOS platforms
from the DT based ones. Turning off CONFIG_EXYNOS_ATAGS disables
all platforms that are not yet converted to DT, and we can
have code that relies on DT checking for this symbol being
disabled.

The EXYNOS platform is moving towards being completely probed
through device tree. This enables support for board files using
the traditional ATAGS boot format.
Note that this option is not available for multiplatform builds.
