lenovo/x60/romstage.c: Collect timestamps in romstage

Collect early timestamps in Lenovo X60’s romstage like the Lenovo T60
    does. Selecting the option `COLLECT_TIMESTAMPS` in Kconfig and then
    doing `cbmem --timestamps` should output the timestamps.

Thanks to Nico Huber’s work setting this up for the ICH7 and implementing
    it for the T60, all what was needed to do, was to do the equivalent
    changes for the X60 as for the T60 in commit 44c392f8 [1].
