From: Dietmar Eggemann <dietmar.eggemann@arm.com>

To enable the parsing of clock frequency and cpu efficiency values
inside parse_dt_topology [arch/arm/kernel/topology.c] to scale the
relative capacity of the cpus, this property has to be provided within
the cpu nodes of the dts file.

The patch is a copy of commit 8f15973ef8c3 ("ARM: vexpress: Add CPU
clock-frequencies to TC2 device-tree") taken from Linaro Stable Kernel
(LSK) massaged into mainline.
