Felix Held 1ed5a63c8c soc/amd/cezanne: add GNB IOAPIC support
To configure and enable the IOAPIC in the graphics and northbridge (GNB)
container, FSP needs to write an undocumented register, so pass the GNB
IOAPIC MMIO base address to make it show up at that address.

BUG=b:187083211
TEST=Boot guybrush and see IO-APIC initialized
IOAPIC[0]: apic_id 16, version 33, address 0xfec00000, GSI 0-23
IOAPIC[1]: apic_id 17, version 33, address 0xfec01000, GSI 24-55
