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.
