Subject: drm/amdgpu: force pa_sc_tile_steering_override to 0 for navy_flounder
Git-commit: 8f8463dddcadeb83a3ea117661407893b6ee29fa
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
pa_sc_tile_steering_override is only programmable for
gfx10.0/10.1/10.2, and navy_flounder has the same gfx10.3 IP
with sienna_cichlid.
