The Exynos Power Management Unit (PMU) drivers contain quite large static arrays of register values necessary for given Exynos SoC to enter low power mode. All this data is useless for ARMv8 SoC like Exynos5433, because the image will not be shared between ARMv7 and ARMv8. Add additional Kconfig symbol for selecting the SoC-specific driver addons thus skipping the useless data in the final image (this is similar approach to chosen for Exynos clock controller drivers): - exynos-pmu driver will be compiled on both architectures ARMv7 and ARMv8, - additional driver_data for ARMv7 SoCs will not be built on ARMv8 and a macro will return NULL for them in of_device_id - this should be safe as these compatibles cannot match on ARMv7 and driver anyway handles NULL driver_data, - on ARMv8 compile only exynos-pmu driver which exposes the syscon-regmap for PMU address space.
