timestamps: You can never have enough of them!
Now that we have timestamps in pre-RAM stages, let's actually make use of them. This patch adds several timestamps to both the bootblock and especially the verstage to allow more fine-grained boot time tracking. Some of the introduced timestamps can appear more than once per boot. This doesn't seem to be a problem for both coreboot and the cbmem utility, and the context makes it clear which operation was timestamped at what point. Also simplifies cbmem's timestamp printing routine a bit, fixing a display bug when a timestamp had a section of exactly ",000," in it (e.g. 1,000,185). BRANCH=None BUG=None TEST=Booted Pinky, Blaze and Falco, confirmed that all timestamps show up and contained sane values. Booted Storm (no timestamps here since it doesn't support pre-RAM timestamps yet).
