The ARMv8 Exynos family SoCs in Linux kernel are currently:
 - Exynos5433 (controlled by ARCH_EXYNOS),
 - Exynos7 (controlled by ARCH_EXYNOS7).

It duplicates Kconfig symbols unnecessarily, so consolidate them into
one ARCH_EXYNOS. Future SoCs could fall also under the ARCH_EXYNOS
symbol.

The commit should not bring any visible functional change.

When I sent the EXYNOS5433 patch[1], we don't want to add the each config
for each Exynos SoC. So, I think this patch is good to use only one ARCH_EXYNOS config
for all ARMv8 Exynos SoC.

I think this basically matches the general recommendation for ARM64,
so excluding the single nitpick inline and assuming that, after this
patch, grep ARCH_EXYNOS7 gives no results:

nit: Sounds a little bit strange. Maybe "This enables support for
ARMv8 based Samsung Exynos SoC family"?
