[RFC PATCH 6/6] drivers: base: arch_topology.c: Enable EAS for arm/arm64 platforms

[Dietmar Eggemann]

From: Quentin Perret <quentin.perret@xxxxxxx>

Energy Aware Scheduling (EAS) has to be started from the arch code.
This commit enables it from the arch topology driver for arm/arm64
systems, hence enabling a better support for Arm big.LITTLE and future
DynamIQ architectures.
