soc/amd/*/northbridge,root_complex: simplify GNB IOAPIC resource index 

In the northbridge's and root complex' read_resources function, the
GNB IOAPIC resource used MMIO base address of the GNB IOAPIC as index
which might be misleading. Instead use idx++ as a unique index for this
resource.

TEST=Resource allocator doesn't complain and no related warnings or
errors in dmesg. The update_constraints console output changes like
expected:

Before:  PCI: 00:00.0 fec01000 base fec01000 limit fec01fff mem (fixed)
After: PCI: 00:00.0 0d base fec01000 limit fec01fff mem (fixed)
