    mainboard/intel/galileo: Enable minimal ACPI tables
    
    Enable the minimal ACPI tables.  Initialize the FADT header and provide
    an empty DSDT.
    
    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"
    *  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
    *  Build EDK2 CorebootPayloadPkg/CorebootPayloadPkgIa32.dsc to generate
    UEFIPAYLOAD.fd
    *  Edit .config file and add the following lines:
       * CONFIG_PAYLOAD_ELF=y
       * CONFIG_PAYLOAD_FILE="path to UEFIPAYLOAD.fd"
    *  Testing successful if:
       *  Outputs multiple lines of debug serial text
