If it were taking that long to get to romstage... that would imply the
bootblock takes 2x longer than the whole coreboot on some boards ^^

You could try to get your hands on the first timestamp and then delay
appropriately. I assume, everything else would result in an `if` mess.

Btw. when I first saw this, I thought "why doesn't he do it in
bootblock_mainboard_early_init()?". Guaranteed to run only once
per boot and explicitly executed before console_init().
