Subject: drm/amdgpu: let mode2 reset fallback to default when failure
Git-commit: dac6b80818ac2353631c5a33d140d8d5508e2957
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
- introduce AMDGPU_SKIP_MODE2_RESET flag
- let mode2 reset fallback to default reset method if failed
v2: move this part out from the asic specific part
