soc/amd/picasso/acpi: Change PCI0 BAR window

Browse Source 
Picasso currently declares the BAR region between TOM and IO_APIC_ADDR.
This region includes MMCONF. We don't want to map any PCI BARs in this
region. This also matches what intel does.
See soc/intel/braswell/acpi/southcluster.asl for an example.
