soc/intel/xeon_sp/cpx: use HOB_TYPE_GUID_EXTENSION to interpret platform HOBs

Platform HOBs (in particular IIO_UDS and MemoryMap HOBs) are of HOB type
HOB_TYPE_GUID_EXTENSION, therefore they do not have resource structure.

Remove the erroneous code related to resource structure.

Remove unnecessary function prototypes from header files, and define them
as static in hob_display.c.

Since we have the HOB pointer, there is not need to search HOB by GUID.
Remove unnecessary calling of fsp_find_extension_hob_by_guid().
