Lee Leahy 9fd0895cb4 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
