[PATCH v4 3/3] arm64: EXYNOS: Consolidate ARCH_EXYNOS7 symbol into ARCH_EXYNOS

From: Krzysztof Kozlowski
Date: Wed Jan 27 2016 - 19:36:21 EST


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.
