cpufreq: intel_pstate: Remove EPB-related code
The intel_pstate driver does not enable HWP mode when CPUID.06H:EAX[10]
is not set, indicating that EPP (Energy Performance Preference) is not
supported by the hardware.
When EPP is unavailable, the system falls back to using EPB (Energy
Performance Bias) if the feature is supported. However, since the
intel_pstate driver will not enable HWP in this scenario, any EPB-related
code becomes unreachable and irrelevant. Remove the EPB handling code
paths simplifying the driver logic and reducing code size.
