Bluetooth: Allow combination of BDADDR_PROPERTY and INVALID_BDADDR quirks

When utilizing BDADDR_PROPERTY and INVALID_BDADDR quirks together it
results in an unconfigured controller even if the bootloader provides
a valid address. Fix this by allowing a bootloader provided address
to mark the controller as configured.
