From: Perry Yuan <Perry.Yuan@amd.com>
Introduce AMD CPU frequency boosting control sysfs entry which used for switching boost on and boost off.
If core performance boost is disabled while a core is in a boosted P-state, the core automatically transitions to the highest performance non-boosted P-state The highest perf and frequency will be limited by the setting value.
