soc/intel/common: Use SoC specific routine to read/write MTRRs
The registers associated with the MTRRs for Quark are referenced through
a port on the host bridge. Support the standard configurations by
providing a weak routines which just do a rdmsr/wrmsr.
Testing:
* Edit the src/mainboard/intel/galileo/Makefile.inc file
* Add "select DISPLAY_MTRRS"
* Add "select HAVE_FSP_PDAT_FILE"
* Add "select HAVE_FSP_RAW_BIN"
* Add "select HAVE_RMU_FILE"
* 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 MTRRs are displayed and
* The message "FspTempRamExit returned successfully" is displayed
TEST=Build and run on Galileo
