[CI,0/2] Force CCS mode to the maximum

Hi,

There has been a regression apparently caused by the CCS mode
forced to be 1[*]. But, because I think the kernel approach is
correct and there might be something hardcoded in userspace, I
want to show that with this series we won't see the regression.

What this series does is to force CCS mode to 4 (or to the
maximum). This way we will understand whether the issue comes
because of disabling the automatic load balancing or by forcing
it to use only one CCS.

Thanks gnattu for your report, i will appreciate if you can give
this a try.

Andi
