[coreboot] [PATCH] Hardcode PCI devices in Intel southbridge early init code

[Ed Swierk]

The early init code of several Intel southbridge chipsets calls
pci_locate_device() to locate the SMBus controller and LPC bridge
devices on the PCI bus. Since these devices are always located at a
fixed PCI bus:device:function, the code can be simplified by
hardcoding the devices.
