[PATCH 1/7] cpufreq: amd-pstate: remove set_boost callback for passive mode

From: Perry Yuan
Date: Fri Jan 26 2024 - 04:11:07 EST


From: Perry Yuan <Perry.Yuan@xxxxxxx>

The following patches will enable `amd-pstate` CPU boost control method
which will not need this common boost control callback anymore, so we
remove the legacy set_boost interface from amd-pstate driver.
