    soc/intel/quark: Enable ESRAM
    
    The Quark SoC uses ESRAM instead of cache-as-RAM.  This code requires
    that utils/xcompile/xcompile change the machine architecture from i686
    to i586 to ensure that the Quark does not attempt to execute unsupported
    instructions:
    
    *  Adjust Makefile.inc to add the RMU to the coreboot image
    *  Add code to enable the ESRAM
    
    Directly use the QuarkSocPkg/QuarkNorthCluster/Include/QuarkNcSocId.h
    file from the EDK2 tree (https://github.com/tianocore/edk2.git) to
    enable
    easy differences and correct issues in coreboot that were found in EDK2.
    
    Testing on Galileo:
    *  Edit the src/mainboard/intel/galileo/Makefile.inc file
       *  Add "select ADD_RMU_FILE"
    *  Place the rmu.bin file in the location specified by CONFIG_RMU_FILE
    *  Remove power from the board
    *  Apply power to the board
    *  Testing is successful if the SD LED is on indicating that the end of
       esram_init.inc was reached
