Hi Krzysztof,

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.
