IntelFsp2WrapperPkg: Save FspHobListPtr right after FspMemoryInit exits 

Save FspHobList pointer to HOB right after FspMemoryInit exits so that
FspHobList pointer is available when performing platform related reset
in CallFspWrapperResetSystem(). Some platforms may consume FSP HOBs
prior to performing platform related reset.
