util/cbmem: Scale time stamp values correctly

Commit c49014e (timestamp: add tick frequency to exported table)
    refactors the code, but forgets to correctly scale the frequency to
    megahertz, where the value is read from sysfs, so that printing time
    stamp information shows milliseconds instead of microseconds, as can be
    seen on the output `cbmem -t` for the ASRock E350M1 below.

```
       0:1st timestamp                                     515
      10:start of ramstage                                 515 (0)
      30:device enumeration                                515 (0)
      40:device configuration                              610 (94)
      50:device enable                                     614 (4)
      60:device initialization                             624 (9)
      70:device setup done                                 639 (14)
      75:cbmem post                                        844 (205)
      80:write tables                                      844 (0)
      90:load payload                                      849 (4)
      15:starting LZMA decompress (ignore for x86)         849 (0)
      16:finished LZMA decompress (ignore for x86)         869 (20)
      99:selfboot jump                                     869 (0)

Total Time: 350
    ```

So scale the return value correctly to megahertz, by dividing it with
    1000.

```
