Subject: [PATCH v4 6/7] cpufreq: amd-pstate: remove legacy set_boost callback for passive mode

With new freqency boost interface supported, legacy boost control
doesn't make sense any more which only support passive mode.
so it can remove the legacy set_boost interface from amd-pstate driver
in case of there is conflict with new boost control logic.
