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.
