drm/amd/display: add Pollock IDs, fix Pollock & Dali clk mgr construct

2020-01-14T15:18:10Z

[WHY] Only a single voltage level should be available to Pollock (min level) Pollock & Dali get misidentified as Renoir, use wrong clk mgr constructor [HOW] Add provided Pollock IDs to ASIC Rev. ID list. Create new Pollock ASIC RID check, fix RV2 & Dali ASIC checks. Check RID and set max voltage level to 0 if Pollock is detected. Work around broken ASICREV_IS_RENOIR, IS_RAVEN2, etc. checks by performing Dali/Pollock checks before they can be misidentified as RN.
