[PATCH v14 5/5] cpufreq: Only disable boost during cpu online when using frequency tables

The behavior introduced in commit f37a4d6b4a2c ("cpufreq: Fix per-policy
boost behavior on SoCs using cpufreq_boost_set_sw()") sets up the boost
policy incorrectly when boost has been enabled by the platform firmware
initially even if a driver sets the policy up.

This is because there are no discrete entries in the frequency table.
Update that code to only run when a frequency table is present.
