Subject: drm/amd/display: Honor pplib stutter mask for all ASICs in DC
Git-commit: 1bc460a45b9746db4b0e6be46c122c377120aace
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

[Why]
We were only setting this mask for DCN, but should really use it
universally for all ASICs.

[How]
Move the assignment out of the Raven switch statement for all ASICs
other than Stoney and Carrizo.

v2: Keep stutter always on for Carrizo and Stoney (Alex)
