Commit fe974716 ("rockchip: rk3288: Allow setting up clocks in
U-Boot proper") fixes some clock issues when chainloading U-Boot on
rk3288 chromebooks. 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.
