Part of that change is still available in veyron's board_early_init_r() function. Since chain-loading U-Boot proper from vendor firmware is possible on gru boards as well, do the same thing for them too. On rk3399, this needs to detect whether SPL was run via handoff, so enable that and bloblist kconfigs it needs for chromebook_bob.
