soc/amd/*/root_complex: introduce and use domain_iohc_info struct

Instead of implementing the functions get_iohc_misc_smn_base and
get_iohc_fabric_id in the SoC code, move those functions to the common
AMD code, and implement get_iohc_info in the SoC code that returns a
pointer to and the size of a SoC-specific array of domain_iohc_info
structs that contains the info needed by the common code instead. This
allows to iterate over the domain_iohc_info structs which will be used
in a later patch to find the PSP MMIO base address in both ramstage and
smm.

TEST=Mandolin still boots and all non-PCI MIO resources are still
reported to the resource allocator
