When one of the General-Purpose PCIe bridges is not used, it doesn't show up on the PCI bus at all, so coreboot notes it as an issue in the devicetree. This happens even if the device is marked as off. To solve this, we're marking the GPP bridge devices in devicetree as hidden, so they'll only show up in devicetree if they're actually used on a mainboard. BUG=None TEST=Don't see the "PCI: Leftover static devices:" warning for these in the boot console.
