tools/power turbostat: correctly decode of ENERGY_PERFORMANCE_BIAS
When EPB is 0xF, turbosat was incorrectly describing it as "custom" instead of calling it "powersave": < cpu0: MSR_IA32_ENERGY_PERF_BIAS: 0x0000000f (custom) > cpu0: MSR_IA32_ENERGY_PERF_BIAS: 0x0000000f (powersave) Signed-off-by: Len Brown <len.brown@intel.com>
