[PATCH 00/27] cpufreq: Stop validating cpufreq table in drivers

Hi,

A patchset [1] sent last week already updated the cpufreq core to start
validating cpufreq table if the policy contains a valid
"policy->freq_table" pointer.

This series updates all such drivers to stop validating the cpufreq
table directly and let only the core handle it.

It depends on the previous series [1] and two cleanup patches [2][3] and
is rebased over 4.16-rc3.

It is already tested by the 0-day testing infrastructure and no issues
were reported.
