In the RS780/RS690 ProgK8TempMmioBase() function, the dst-link field is set 

to zero, so for boards with RS780 not on CPU's HT chain 0, the function will
mis-configure the MMIO dst-link routing, and the following enable_pcie_bar3()
function will hang when it visits the MMIO.

The following patch fixes the problem, and is tested on a K8 board with RS780
on HT chain 1.
