drm/amd/powerplay: update cached feature enablement status V3
Need to update in cache feature enablement status after pp_feature
settings. Another fix for the commit below:
drm/amd/powerplay: implment sysfs feature status function in smu
V2: update smu_feature_update_enable_state() and relates
V3: use bitmap_or and bitmap_andnot
