drivers/intel/fsp2_0: Add display HOB support

Add support to display the HOBs returned by FSP:
* Add Kconfig value to enable HOB display
* Move hob_header, hob_resource and uuid_name structures into util.h
* Move hob_type enum into util.h
* Remove static from the debug utility functions
* Add fsp_ prefix to the debug utility functions
* Declare the debug utility functions in debug.h
* Add HOB type name table
* Add more GUID values
* Add new GUID name table for additional GUIDs
* Add routine to convert EDK-II GUID into a name
* Add SOC specific routine to handle unknown GUID types
* Add routine to convert HOB type into a name
* Add SOC specific routine to handle unknown HOB types
* Add routine to display the hobs

TEST=Build and run on Galileo Gen2
