mb/google/brya/var/kano: Disable unused PCIE root port in devicetree
The baseboard enables PCIe RPs 6, 8 and 9, but kano doesn't use
these. Having them enabled will occasionally cause suspend
attempts to fail, therefore disable them in the overridetree.
BUG=b:203389490 b:192370253
TEST=FW_NAME=kano emerge-brya coreboot and verify it builds
without error.
