mb/google/kahlee/*/devicetree: disable unused PCIe root ports
Disable the unused PCIe root ports that are disabled in the PCIe port corresponding descriptor list passed to AGESA/binaryPI. This descriptor list is in src/mainboard/google/kahlee/variants/baseboard/OemCustomize.c and it only has B0D2F2 (gpp_bridge_1) and B0D2F4 (gpp_bridge_3) enabled. Since the PCIe engines marked as unused in the port descriptor list won't show up as PCI devices, don't enable those PCI devices in the devicetree so that coreboot won't complain about static PCI devices not being found on the PCI bus.
