Subject: drm/amd/pm: drop unneeded smu->sensor_lock
Git-commit: 56383e8f4d296a33cc5b2a11864025d8205e9438
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
As all those related APIs are already well protected by
adev->pm.mutex and smu->message_lock.
