From: James Zhu <James.Zhu@xxxxxxx>
[WA] Increase AMDGPU_MAX_HWIP_RINGS to 64 to support more compute
ring resource. Later need redesign with queue/prirority/scheduler
factors to reduce AMDGPU_MAX_HWIP_RINGS.
This is just a workaround for internal use and not meant for upstreaming.
The array is used for the load balancing between scheduler instances.
Since we don't want to load balance between different partitions we
should not need to increase this.
