mb/google/brya: Update state of BB_RT_FORCE_PWR gpios
This GPIO is used to force the USB retimers on Type-C ports to stay in a
powered state and can be used e.g., during a firmware update to the
retimer to force power on even when no device may be connected to the
port. However, its power rail is controlled elsewhere and coreboot is
not applying a FW update, so this GPIO should be driven low instead.
