ASUS F2A85-M: Correct and clean up PCIe config
Assign the lanes correctly to the physical slots on the motherboard in `PlatformGnbPcie.c`. • UMI is connected to SB via 4x PCIe bridge 8. • The blue x16 slot is not shared with DDI and is routed through PCIe bridge 2. • The black x8 slot is in fact a x4 slot and uses all 4 GPPs from the CPU. • Assume that DDI is on out-of-PCIe-band lanes.
