Smatch complains that we need to initialized "*cap" otherwise it can
lead to an uninitialized variable bug in the caller.  This seems like a
reasonable warning and it doesn't hurt to silence it at least.

drivers/gpu/drm/amd/amdgpu/vi.c:767 vi_asic_reset_method() error: uninitialized symbol 'baco_reset'.

Fixes: 425db2553e43 ("drm/amdgpu: expose BACO interfaces to upper level from PP")
