    mainboard/intel/galileo: Enable Serial Output
    
    Add the code to enable debug serial output using HSUART1:
    
    *  Enable the code using Kconfig value ENABLE_BUILTIN_HSUART1
    *  Specify the portion of ESRAM to be used by romstage
    *  Initialize the debug serial port
    
    Testing:
    *  Edit the src/mainboard/intel/galileo/Makefile.inc file
       *  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 serial output is present on HSUART1 at
    115200 baud, 8-bit, no parity
    
    TEST=Build and run on Galileo
