soc/intel: Unify `timestamp.inc` These files are actually indentical, but unfortunately, the formatting was changed without caring for the already present files. Fix that. Use the license formatting where less lines are used. The next step is to put that in a common location.

* because the bootblock isn't being compiled with MMX support so mm1 and
* mm2 will be preserved into romstage.

baytrail: start collecting timestamps This commit always selects COLLECT_TIMESTAMPS and starts tracking TSC values from the early stages of bootblock. The initial timestamp value is saved in mm0 and mm1 while in bootlbock. This approach works because romcc is not configured to use mmx registers for its compilation. Additionally, the romstage api with the mainboard was changed to always pass around a pointer to a romstage_params structure as the timestamps are saved in there until ram is up. BUG=chrome-os-partner:22873 BRANCH=None TEST=Built and booted with added code to print out timestamps at end of ramstage. Everything looks legit.
