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.
