    drivers/intel/fsp2_0: Add UPD display support
    
    Add UPD display support:
    *  Add a Kconfig value to enable UPD value display
    *  Add a routine to display a UPD value
    *  Add a call before MemoryInit to display the UPD parameters
    *  Add a routine to display the architectural parameters for MemoryInit
    *  Add a weak routine to display the other UPD parameters for MemoryInit
    *  Add a call before SiliconInit to display the UPD parameters
    *  Add a weak routine to display the UPD parameters for SiliconInit
    
    TEST=Build and run on Galileo Gen2.
