Subject: drm/amdgpu: support new mode-1 reset interface (v2)
Git-commit: 3ebd8bf02380ddc32556ee87077db3917ccff40c
Patch-mainline: v5.17-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
If gpu reset is triggered by ras fatal error, tell it to smu in mode-1
reset message.
v2: move mode-1 reset function to aldebaran_ppt.c since it's aldebaran
specific currently.
