util/cbmem: accumulate total time for all entries

Display the total accumulated time using each timestamp
entry. It purposefully doesn't take into account the first
timestamp because that can be a platform dependent value
that may not contribute to the concept of "total".

BUG=None
BRANCH=None
TEST=Ran cbmem on glados where TSC doesn't reset to 0 on
     reboots. Clear total value given at end.
