[PATCH PATCH 2/9] cpufreq: intel_pstate: Use topology_cpu_type() to get cpu-type

[Pawan Gupta <pawan.kumar.gupta@linux.intel.com>]

Intel pstate driver uses hybrid_get_type() to get the cpu-type of a given
CPU. It uses smp_call_function_single() which is sub-optimal and can be
avoided as cpu-type is also available in the per-cpu topology structure.

Use topology_cpu_type() to get the cpu-type.
