mainboard/jetway/nf81-t56n-lf: Fix GPP missing CLK on PCI bridge. 

The platform dependent mainboard.c was incorrectly disabling the
second clock signal feeding the GPP ports. This results in
spurious hangs by calling the set_pcie_dereset() SB CIMx callback
many times. This also stops coreboot from finding the second NIC
behind the pci 15.0 bridge.
