[coreboot] Systemagent hangs on PCH init with H61 chipset

[Alex G.]

Is there anything special that systemagent needs before it will actually
do something useful. I've tried to run it on a board with a H61 chipset,
and it just hangs at "System Agent: Initializing PCH". I remember Damien
had a similar problem a few months back.
