soc/amd/*/root_complex: use FSP HOB iterator functions
Use the newly added functions to iterate over the FSP HOBs to report the
resources used by FSP to the resource allocator instead of open coding
the iteration over the HOBs in the SoC code.
TEST=Patch doesn't change reported resources on Mandolin
