mainboard/asus/f2a85-m: Correct APIC routing for Bus 0, Dev 21

The "Bus 0, Dev 21 PCIE Bridge" entry doesn't match the DSDT from my
BIOS. It looks like this entry was erroneously copied from the entry
for "Bus 0, Dev 20" without rotating the IRQ numbers.
The other entries match my ASUS BIOS and the usual rotation pattern.
