rockchip: rk3399: Init clocks in U-Boot proper if SPL was not run

It's possible to chainload U-Boot proper from the vendor firmware in
rk3399 chromebooks, but the way the vendor firmware sets up clocks is
somehow different than what U-Boot expects. This causes the display to
stay devoid of content even though vidconsole claims to work (with
patches in process of being upstreamed).

This is meant to be a rk3399 version of commit d3cb46aa8c41 ("rockchip:
Init clocks again when chain-loading") which can detect the discrepancy,
but this patch instead checks whether SPL (and therefore the clock init)
was run via the handoff functionality and runs the init if it was not.
