Use the new common AMD code that gets the usable non-fixed MMIO windows from the data fabric MMIO decode registers and generate the PCI0 _CRS ACPI code based on those regions. For a more detailed description see the corresponding patch that changes the Picasso code to use this new code. In contrast to the Picasso code, this change will drop the unneeded _STA method inside the PCI0 scope which wasn't present in Picasso's ACPI code before it got replaced by the SSDT that gets generated by amd_pci_domain_fill_ssdt.
