transport: Bridge build workaround

Function ble_ll_data_buffer_overflow() and ble_ll_hw_error() are executed
from host code, but those are controller functions. They would only work
when host and controller runs on same CPU.
In bridge build when controller code can't be executed this way two transports
(nrf5340/dialog_cmac) provide those functions so UART can be used in bridge
configuration.
This is just workaround till functions are implemented or other way of signaling
those errors is established.
