soc/amd/block/ivrs: Generalize IVRS table generation
This commit introduces a refactored version of the IVRS (I/O
Virtualization Reporting Structure) table generation. The main objective
of this refactoring is to generalize the process of generating the IVRS
table based on the IOMMU (Input/Output Memory Management Unit) domains
and their corresponding resources.
