Alex Deucher a7049de1e8 drm/amdgpu/gfx9: new queue policy, take first 2 queues of each pipe
Instead of taking the first pipe and giving the rest to kfd, take the
first 2 queues of each pipe.

Effectively, amdgpu and amdkfd own the same number of queues. But
because the queues are spread over multiple pipes the hardware will be
able to better handle concurrent compute workloads.

amdgpu goes from 1 pipe to 4 pipes, i.e. from 1 compute threads to 4
amdkfd goes from 3 pipe to 4 pipes, i.e. from 3 compute threads to 4

Pipes provide better concurrency than queues, therefore we want to make

therefore we don't want adjacent rings to belong to the same pipe.
