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.

94 The EXYNOS platform is moving towards being completely probed
95 through device tree. This enables support for board files using
96 the traditional ATAGS boot format.
