[PATCH] drm/amd/powerplay: make fiji command table constant.

[PATCH] drm/amd/powerplay: make fiji command table constant.

[Dave Airlie]

From: Dave Airlie <airlied@redhat.com>

On my otherly hacked up kernel module this does:
1090519	 141169	   1532	1233220	 12d144	drivers/gpu/drm/amd/amdgpu/amdgpu.ko

1213447	  18225	   1532	1233204	 12d134	drivers/gpu/drm/amd/amdgpu/amdgpu.ko

clearly having less data is better.

Oh ignore these, I see Nils has sent some that do the same and a lot more!
