ACPI: CPPC: add sysfs entry for guaranteed performance 



Expose the CPPC guaranteed performance as reported by the platform through
GuaranteedPerformanceRegister.

The current value is already read in cppc_get_perf_caps() and stored in
struct cppc_perf_caps (to be used by the intel_pstate driver), so only the
attribute itself needs to be defined.
