cpufreq: Fix per-policy boost behavior on SoCs using cpufreq_boost_set_sw()
In the existing code, per-policy flags don't have any impact i.e.
if cpufreq_driver boost is enabled and boost is disabled for one or
more of the policies, the cpufreq driver will behave as if boost is
enabled.
Fix this by incorporating per-policy boost flag in the policy->max
computation used in cpufreq_frequency_table_cpuinfo and setting the
default per-policy boost to mirror the cpufreq_driver boost flag.
Fixes: 218a06a79d9a ("cpufreq: Support per-policy performance boost")
