drm/amdgpu: use node_id and node_size to calcualte dram_base_address
physical_node_id * node_segment_size should be the dram_base_address for current gpu node in xgmi config Signed-off-by: Hawking Zhang <Hawking.Zhang@amd.com> Reviewed-by: John Clements <john.clements@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
