Subject: drm/amdgpu: move PX checking into amdgpu_device_ip_early_init
Git-commit: 901e2be20dc55079997ea1885ea77fc72e6826e7
Patch-mainline: v5.18-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
We need to set the APU flag from IP discovery before
we evaluate this code.
