Currently, when booting a subset of cpus in policy->related_cpus, and
entering the CPPC FIE initialization process during CPU initialization,
there are repeated warnings: "read perf counters failed".

This occurs because reading performance feedback counters from offline
or low-power idle CPUs may return 0, which is interpreted as an error
and results in returning -EFAULT each time this happens.

Remove warning when reading from offline cpus, and changes the print
level to debug in case the cpu is in low-power idle state.

  cpufreq: CPPC: Don't warn on failing to read perf counters on offline
    cpus
  cpufreq: CPPC: Fix error handling in cppc_scale_freq_workfn()
