Subject: drm/amd/powerplay: add dummy pp table for raven. (v2)
Git-commit: 3b4ca9e6494d19b152d1833fede533835e7b7c18
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

As there is no PPTable in RV, it is difficult to
cleanly decouple PPTABLE functionality in existing
codes.

v2: agd: squash in clean build fix
