Move subsystem IDs to devicetree.cb

A while back coreboot was changed to read the subsystem IDs from
devicetree.cb to allow each onboard PCI device to have its own
subsystem id. When we originally branched, this was not the case,
and the sandybridge/ivybridge mainboards have not been updated yet.
Also, drop the subsystem ID from Emerald Lake 2, since it's not a
Google device.
