ACPI / CPPC: add sysfs entries for CPPC perf capabilities
Computed delivered performance using CPPC feedback counters are in the CPPC abstract scale, whereas cppc_cpufreq driver operates in KHz scale. Exposing the CPPC performance capabilities (highest,lowest, nominal, lowest non-linear) will allow userspace to figure out the conversion factor from CPPC abstract scale to KHz. Also rename ctr_wrap_time to wraparound_time so that show_cppc_data() macro will work with it. Signed-off-by: Prashanth Prakash <pprakash@codeaurora.org> Signed-off-by: Rafael J.
