soc/amd/common/root_complex: add function to report non-PCI resources

Introduce the common read_non_pci_resources function to read the base
address of the non-PCI resources within the MMIO regions configured in
the data fabric registers and pass that info to the resource allocator.
Each SoC will need to provide implementations for get_iohc_misc_smn_base
and get_iohc_non_pci_mmio_regs in order for read_non_pci_resources to
know the SoC-specific base addresses, register offsets and MMIO region
sizes. In case of SoCs with only one PCI root domain, the domain
parameter of get_iohc_misc_smn_base will be unused, but in the case of
SoCs with more than one PCI root domains, this parameter will be used by
the SoC-specific code.
