This makes sure that the resource allocator won't use this address range
for anything else. In the systems I looked at, this was between the end
of the above 4GB memory and the beginning of the above 4GB PCI BAR MMIO
region, but better reserve it here so nothing else will get allocated
there if this expectation isn't met.
TEST=Reserved region is printed in the console logs:

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.

Use the newly added functions to iterate over the FSP HOBs to report the
resources used by FSP to the resource allocator instead of open coding
the iteration over the HOBs in the SoC code.

When no HOB list is found, not only adding the resources reported by the
FSP were skipped, but also adding the GNB IOAPIC resource was skipped.
Fix this bug by moving the reporting of the GNB IOAPIC resource before
the resources reported in the FSP HOBs to not skip the IOAPIC resource
when there's no HOB list.
