We have a timestamp from before cache-as-ram setup saved in the MMX
registers. Recover that timestamp, and use it as the base timestamp
rather than letting lib/bootblock.c use a late timestamp.
This allows more accurate profiling of the boot flow, since CAR setup
time is no longer excluded from the timing information.
