Subject: [PATCH V3 5/7] drm/amd/pm: drop the cache for enabled ppfeatures
The following scenarios make the driver cache for enabled ppfeatures
outdated and invalid:
- Other tools interact with PMFW to change the enabled ppfeatures.
- PMFW may enable/disable some features behind driver's back. E.g.
for sienna_cichild, on gfxoff entering, PMFW will disable gfx
