cpufreq: intel_pstate: Configurable algorithm to get target pstate
Target systems using different cpus have different power and performance requirements. They may use different algorithms to get the next P-state based on their power or performance preference. For example, power-constrained systems may not want to use high-performance P-states as aggressively as a full-size desktop or a server platform. A server platform may want to run close to the max to achieve better performance, while laptop-like systems may prefer sacrificing performance for longer battery lifes. For the above reasons, modify intel_pstate to allow the target P-state selection algorithm to be depend on the CPU ID.
