nb/amd/pi/00730F01/northbridge.c: refactor IVRS generation

Use defined structures to assemble IVRS and IVHD entries. Additionally
assemble IVHD type 11h which supersedes IVHD type 10h. In order to
utilize all IOMMU features firmware should also expose IVHD type 11h.
The new type is already supported and parsed since Xen 1.13. IVHD
type 10h should still be present for backwards compatibility.

TEST=boot PC Engines apu2 and disassemble IVRS using newest IASL,
boot Xen 1.13 or newer with debug enabled and see IVRS IVHD 11h parsed
in xl dmesg
