The following patch implements Opteron Fam 10 rev D (aka Istanbul)
support for coreboot.  I have not updated MAX_CPUS for all fam10
mainboards, but it might make sense to multiply those by 1.5.

I assume the line
pci_write_config32(NODE_PCI(nodeid, 0), 0x168, dword);
should be put outside the loop.

Everything seems to be fine. I don't have Istanbul to test. I have
read every changes and they all look good.
