[PATCH v10 03/12] cpufreq: intel_pstate: use common macro definition for Energy Preference Performance(EPP)

Perry Yuan

make the energy preference performance strings and profiles using one
common header for intel_pstate driver, then the amd_pstate epp driver can
use the common header as well. This will simpify the intel_pstate and
amd_pstate driver.
