mb/google/octopus/variants/foob: Disable xHCI compliance mode
When any USB image disk is connected to the DUT through
HUAWEI/APPLE Dongle, press Ctrl + u on the dev screen,
it cannot boot from USB.
We found the SS hub cannot be enumerated. So disable xHCI
compliance mode.
BRANCH=octopus
BUG=b:155347573
TEST=Confirm successful boot from USB
