[PATCH v4 5/9] power/cppc: remove redundant lcore ID checks

Now that the cpufreq framework validates the lcore ID using
RTE_POWER_VALID_LCOREID_OR_ERR_RET() before dispatching to any driver,
each individual cpufreq driver no longer needs its own range
check against RTE_MAX_LCORE.
Remove the duplicated lcore ID checks from the cppc cpufreq
driver ops.
