cpufreq: intel_pstate: EAS: Increase cost for CPUs using L3 cache

On some hybrid platforms some efficient CPUs (E-cores) are not connected
to the L3 cache, but there are no other differences between them and the
other E-cores that use L3.  In that case, it is generally more efficient
to run "light" workloads on the E-cores that do not use L3 and allow all
of the cores using L3, including P-cores, to go into idle states.

For this reason, slightly increase the cost for all CPUs sharing the L3
cache to make EAS prefer CPUs that do not use it to the other CPUs of
the same type (if any).
