soc/amd/genoa_poc/domain: refactor read_soc_memmap_resources
To bring genoa_poc more in line with the other AMD SoCs, move the
reporting of the memory map up to cbmem_top from the openSIL-specific
add_opensil_memmap function to read_soc_memmap_resources. This is a
preparation for making this code common for all newer AMD SoCs.
