Subject: Add cpu topology info

We read cpu top[ology info from /sys/devices/system/cpuX/topology.
Packed them into cpu_topology struct. And print in next format.
clusterA:
	coreX
		cpuA
		cpuB
	coreY
		cpuC
		cpuD
clusterB:
        coreS
                cpuE
                cpuF
        coreT
                cpuG
                cpuH
	...

When cpu topology info could be read, CPU idle state is shown
ordered by topology.
When cpu topology info could not be read, CPU idle state is shown
in old order.
