Karel Zak 778254d9a2 lscpu: keep static/dynamic MHz in cputype struct 
The Dynamic and Static MHz are /proc/cpuinfo s390 per-CPU fields, but
we display it as a single value according the first parsed CPU. For
this purpose we store the values from the first CPU in lscpu_cputype.

For -p and -e outputs we will print per CPU values.

Karel Zak fa6a21bf63 lscpu: calculate threads number from type specific values 
Don't use global CPU masks (like "online" or "present") to
calculate type specific number of threads due systems with
mixed CPU types.

It's also necessary to check all thread_siblings maps to get the
highest number, because some threads (CPUs) may be disables, for
example old lscpu calculates number of threads from the cpu0 and
if you disable cpu0's sibling (cpu4):

	CPU(s):                          8
	On-line CPU(s) list:             0-7
	Thread(s) per core:              2        <---
	Core(s) per socket:              4
	Socket(s):                       1

 # chcpu --disable 4
 CPU 4 disabled

	CPU(s):                          8
	On-line CPU(s) list:             0-3,5-7
	Off-line CPU(s) list:            4
	Thread(s) per core:              1        <--- !
	Core(s) per socket:              4
	Socket(s):                       1

because 'thread_siblings' contains only one thread for cpu0:

 # cat /sys/devices/system/cpu/cpu{0,1,2,3,4,5,6,7}/topology/thread_siblings_list
 0
 1,5
 2,6
 3,7
 cat: /sys/devices/system/cpu/cpu4/topology/thread_siblings_list: No such file or directory
 1,5
 2,6
 3,7
