soc/amd/common/fsp: factor out read_fsp_resources from root_complex.c
Factor out the common FSP-specific code to report the usable and
reserved memory resources read from the HOBs that FSP has put into
memory. This both reduces code duplication and also moves FSP-specific
code out of the SoC code into the FSP-specific common AMD SoC code
folder.
