drm/amdgpu: delay ttm buffer func enablement on xgmi
When amdgpu_init_minimal_xgmi is used, SDMA engines init
is delayed so amdgpu_ttm_enable_buffer_funcs must be
called later.
Without this, the check for num_buffer_funcs_scheds will
fail and using ttm buffer funcs later will fail.
Given that amdgpu_ttm_enable_buffer_funcs is a no-op if
amdgpu_in_reset() returns true, the call has to occur
after the reset lock is dropped.
