[ Upstream commit 249b62c448de7117c18531d626aed6e153cdfd75 ]
amd_pstate active mode driver is only compatible with static governors.
Therefore it doesn't need fast_switch functionality. Remove
fast_switch_possible flag from amd_pstate active mode driver.
Fixes: ffa5096a7c33 ("cpufreq: amd-pstate: implement Pstate EPP support for the AMD processors")
