t132: Add timestamp collection support in t132
Add a region TIMESTAMP to store all the timestamps starting from bootblock to end of romstage. At the end of romstage take all the timestamps in TIMESTAMP region and put it into cbmem
BUG=chrome-os-partner:32973 BRANCH=None TEST=Compiles successfully and cbmem -t prints all timestamps
