lscpu: improve bogomips use
...
* keep global (cputype) bogomips
* add per-CPU bogomips
* use bogomips from the first CPU as global (for cputype) if /proc/cpuinfo does not provide global bogomips
* add BOGOMIPS column for to -e/-p output

Let's make it more robust and readable. The sysinfo file on s390 may

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.

lscpu: use cache ID, keep caches independent on CPU type
...
The cache is identified by Type, Level and ID, the ID is unique cache
instance identifier (of the type).
This changes forces lscpu allocate more lscpu_cache instances (than
old version), but now we're ready for arbitrary scenario where
different CPU types share caches and the same cache type uses
different size in different instances, etc.

lscpu: remove obsolete code
...
This is the first step in conversion from old lscpu to the new code.
The patch removes obsolete code from lscpu.c and lscpu.h. The old
output code in lscpu.c is temporary disabled by #ifdef due to
incompatibility between old and new internal APIs -- this will be
changed later by small steps to make all all the changes review-able.
