Subject: drm/amdgpu: initialize cg/pg flags and external rev id for navi12
Git-commit: 74b5e509a082c70fa20798343cd0bbfa532ceda1
Patch-mainline: v5.4-rc1
References: bsc#1152489
don't enable any cg/pg features yet.
v2: calculate external revision id from revision id so that we can
differentiate navi12 A0 from A1 directly.
