Subject: [PATCH v1 1/3] cpufreq: Drop redundant freq_table parameter

Since commit e0b3165ba521 ("cpufreq: add 'freq_table' in struct
cpufreq_policy"),
freq_table has been stored in struct cpufreq_policy instead of being
maintained separately.

However, several helpers in freq_table.c still take both policy and
freq_table as parameters, even though policy->freq_table can always be
used. This leads to redundant function arguments and increases the chance
of inconsistencies.

This patch removes the unnecessary freq_table argument from these functions
and updates their callers to only pass policy. This makes the code simpler,
more consistent, and avoids duplication.
