drm/amdgpu: allocate large structures dynamically
After the structure was padded to 1024 bytes, it is no longer
suitable for being a local variable, as the function surpasses
the warning limit for 32-bit architectures:
drivers/gpu/drm/amd/amdgpu/amdgpu_ras.c:587:5: error: stack frame size of 1072 bytes in function 'amdgpu_ras_feature_enable' [-Werror,-Wframe-larger-than=]
int amdgpu_ras_feature_enable(struct amdgpu_device *adev,
^
Use kzalloc() instead to get it from the heap.
Fixes: a0d254820f43 ("drm/amdgpu: update RAS TA to Host interface")
