util/inteltool: Add more Westmere/Ironlake device IDs

Browse Source 
The host bridge PCI device ID can be changed by the firmware. There
is no documentation about it, though. There's 'official' IDs, which
appear in spec updates and Windows drivers, and 'mysterious' IDs,
which Intel doesn't want OSes to know about and thus are not listed.

For the sake of completeness, add the PCI device IDs for Clarkdale.
Though coreboot only supports Arrandale, both of them are Ironlake.

It is possible that the Management Engine handles changing the PCI
device ID, which would not happen when using a broken ME firmware.
