Subject: drm/amdgpu: Update ring scheduler info as needed
Git-commit: 6cb209ed68e45c8e4b71d97a037ac6b7dbce9b50
Patch-mainline: v6.6-rc1
References: jsc#PED-3527 jsc#PED-5475 jsc#PED-6068 jsc#PED-6070 jsc#PED-6116 jsc#PED-6120 jsc#PED-5065 jsc#PED-5477 jsc#PED-5511 jsc#PED-6041 jsc#PED-6069 jsc#PED-6071
Not all rings have scheduler associated. Only update scheduler data for
rings with scheduler. It could result in out of bound access as total
rings are more than those associated with particular IPs.
