I believe this should be guarded against `SOC_INTEL_COMMON_BLOCK_RUNTIME_CORE_SCALING_FACTORS` Kconfig and use dummy inline function for all the other cases. In that way, the separation would have been clear.

```
#if CONFIG(SOC_INTEL_COMMON_BLOCK_RUNTIME_CORE_SCALING_FACTORS)
enum cb_err soc_read_core_scaling_factors(u16 *performance, u16 *efficient);
#else
static inline enum cb_err soc_read_core_scaling_factors(u16 *performance, u16 *efficient)
{
     *performance = CONFIG_SOC_INTEL_PERFORMANCE_CORE_SCALE_FACTOR;
     *efficient = CONFIG_SOC_INTEL_EFFICIENT_CORE_SCALE_FACTOR;
}
#endif
```
