[coreboot] 870 attempt

Hi,

I've attempted to use the rs780 and sb800 code on a AM3 870 + SB850
board.  Raminit seems to go okay, as does the first bits of ramstage.
However, ramstage fails after the first two passes through
rs780_enable().  It stalls in get_vid_did() reading PCI config space
of device 2 (or 4).  Also, the rs780 HT init code thinks the link should
run at 200MHz, maybe that's related.

I'm aware that this code wasn't exactly intended for the 870,
but maybe someone has some hints of what to try next.
