Subject: drm/amdgpu: enable all 8 sdma instances for Arcturus silicon
Git-commit: 69d4de94f8d35111b3cb54821d3d933b93d87343
Patch-mainline: v5.4-rc1
References: bsc#1152489
The more 6 sdma instances work fine now with DF fix in vbios:
* mmDF_PIE_AON_MiscClientsEnable(0x1c728)=0x3fe(DF_ALL_INSTANCE)
[9:4]MmhubsEnable=3f (change from 0)
