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).
