drivers/intel/fsp2_0: Add timestamps for loading FSPM & FSPS

The loads of the FSPM and FSPS binaries are not insignificant amounts of
time, and without these timestamps, it's not clear what's going on in
those time blocks.  For FSPM, the timestamps can run together to make it
look like that time is still part of the romstage init time.

Example:
   6:end of verified boot                              387,390 (5,402)
  13:starting to load romstage                         401,931 (14,541)
  14:finished loading romstage                         420,560 (18,629)
 970:loading FSP-M                                     450,698 (30,138)
  15:starting LZMA decompress (ignore for x86)         464,173 (13,475)
  16:finished LZMA decompress (ignore for x86)         517,860 (53,687)
...
   9:finished loading ramstage                         737,191 (18,377)
  10:start of ramstage                                 757,584 (20,393)
  30:device enumeration                                790,382 (32,798)
 971:loading FSP-S                                     840,186 (49,804)
  15:starting LZMA decompress (ignore for x86)         853,834 (13,648)
  16:finished LZMA decompress (ignore for x86)         888,830 (34,996)
