tools/power turbostat: call __cpuid() instead of __get_cpuid()

Browse source 
turbostat already checks whether calling each cpuid leavf is legal,
and it doesn't look at the function return value,
so call the simpler gcc intrinsic __cpuid() instead of __get_cpuid().

syntax only, no functional change
