soc/amd/common/data_fabric/domain: report non-PCI MMIO resources 

Call read_non_pci_resources from amd_pci_domain_read_resources to tell
the resource allocator about the non-PCI MMIO regions within the data
fabric MMIO regions so that the allocator won't place any PCI MMIO in
the same areas.

TEST=On Mandolin 3 new non-PCI resources get reported to the allocator:
avoid_fixed_resources: DOMAIN: 0000 04 base fd100000 limit fd1fffff mem (fixed)
avoid_fixed_resources: DOMAIN: 0000 05 base fd000000 limit fd0fffff mem (fixed)
avoid_fixed_resources: DOMAIN: 0000 20000120 base fec01000 limit fec01fff mem (fixed)
