[PATCH POWERTOP] auto tune option to set everything to bad state

Having the command `tuned-adm profile throughput-performance`, it's also

Segfault on ppc64
by Jaroslav Skarvada
PowerTOP crashes on ppc64 machine with 1 idle state, reproducer:
# powertop -t 1 --html
Parameters of the machine are attached.
It seems the problem is caused by the report_display_cpu_cstates()
function from the src/cpu/cpu.cpp file.
On https://github.com/fenrus75/powertop/blob/e8765b5475b22b7a2b6e9e8a031c68a...
it allocates table 2x1, but the table should be 2x2 (header + 1 state), so it
later crashes on
https://github.com/fenrus75/powertop/blob/e8765b5475b22b7a2b6e9e8a031c68a...
where it tries to fill the table.
Unfortunately, the whole reporting code is quite unclear, so I am not sure how
to correctly fix it and not break anything else. The attached patch fixes
the problem for me, but it can have side-effects - feel free to propose
better fix
thanks & regards
Jaroslav
