It's not only power aware scheduling. The scheduler already uses
topology and cache sharing when CONFIG_SCHED_MC and/or
CONFIG_SCHED_SMT are

Power aware scheduling needs the cpu topology information to improve the
cpu scheduler decision making.
For ARM64, we can get the topology from the MPIDR register which defines the
the affinity of processors.
This patch is mainly based on arch/arm/kernel/topology.c written by
