    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.
