mb/google/guybrush: Set BT USB to use GPIO for status
Set the BT USB device to use GPIO for the power status. This causes an
ACPI `_STA()` function to be generated that returns the power status of
the BT USB device, rather than always returning `0x1`. This `_STA()`
function can be used during boot to skip enabling the device (and
performing the associated sleep) if the device is already powered on.
