commit 1478a34470bf4755465d29b348b24a610bccc180 upstream.

commit f81cd793119e ("drm/amd/amdgpu: Fix MES init sequence") caused
a dependency on new enough MES firmware to use amdgpu. This was fixed
on most gfx11 and gfx12 hardware with commit 0180e0a5dd5c
("drm/amdgpu/mes: add compatibility checks for set_hw_resource_1"), but
this left out that GC 11.0.4 had breakage at MES 0x51.

Bump the requirement to 0x52 instead.
