Patrick Rudolph eee5be070a cpu/intel: Use mtrr_use_temp_range()
Cover the SPIROM with a temporary MTRR to speed up SPI flash accesses
after MPinit has removed the MTRR that was installed for postcar stage.

TEST=Booted on Lenovo X220 and measured using cbmem -t:
Before:
  16:finished LZMA decompress (ignore for x86)         1,391,520 (366,351)

After:
  16:finished LZMA decompress (ignore for x86)         1,218,418 (210,054)

Boots 156msec faster than before.
