Subject: drm/amdgpu: remove switch from amdgpu_gmc_noretry_set
Git-commit: e67135571e4073e1ee252f839d7a1ccf10f89410
Patch-mainline: v6.1-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
Simplify the logic in amdgpu_gmc_noretry_set by getting rid of the
switch. Also set noretry=1 as default for GFX 10.3.0 and greater since
retry faults are not supported.
