drm/amdgpu: Use system unbound workqueue for soft IH ring
Allow the kernel to dispatch the soft IH work on other CPUs.
Otherwise it can happen that the soft IH ring fills up
before it actually starts processing anything, which
can easily happen with retry page faults, in which case
the CP repeatedly spams the CPU with a lot of interrupts.
This significantly improves retry page fault handling on
GPUs that don't have the filter CAM and must rely on
software based filtering.
