soc/intel/quark: MTRR support
Add the SoC specific routines to access the MTRR registers. These
registers exist in the host bridge and are not accessible via the
rdmsr/wrmsr instructions.
Testing on Galileo:
* Edit the src/mainboard/intel/galileo/Makefile.inc file
* Add "select ADD_FSP_PDAT_FILE"
* Add "select ADD_FSP_RAW_BIN"
* Add "select ADD_RMU_FILE"
* Add "select DISPLAY_MTRRS"
* Place the FSP.bin file in the location specified by CONFIG_FSP_FILE
* Place the pdat.bin files in the location specified by
CONFIG_FSP_PDAT_FILE
* Place the rmu.bin file in the location specified by CONFIG_RMU_FILE
* Testing is successful if:
* The message "FSP TempRamInit successful" is displayed
