soc/amd: factor out memmap from root_complex

Browse Source 
Now that the SoC-specific memory map is reported on the domain device
instead of the northbridge device, factor out the
read_soc_memmap_resources function from root_complex.c to new memmap.c
file. For now each SoC still has its own memmap.c file, but the plan is
to eventually have a common implementation that works for all AMD family
17h+ SoCs. For that I'll still need to look closer into the differences
between the FSP and the openSIL integration though.
